feat(video_gen): unified video_generate tool with pluggable provider backends (#25126)
* feat(video_gen): unified video_generate tool with pluggable provider backends

One core video_generate tool, every backend a plugin. Mirrors the
image_gen + memory_provider + context_engine architecture: ABC, registry,
plugin-context registration hook, and per-plugin model catalogs surfaced
through hermes tools.

Surface (one schema, every backend):
- operation: generate / edit / extend
- modalities: text-to-video (prompt only), image-to-video (prompt +
  image_url), video edit (prompt + video_url), video extend (video_url)
- reference_image_urls, duration, aspect_ratio, resolution,
  negative_prompt, audio, seed, model override
- Providers ignore unknown kwargs and declare what they support via
  VideoGenProvider.capabilities() — backend-specific quirks stay in the
  backend, the agent learns one tool

Backends shipped:
- plugins/video_gen/xai/  — Grok-Imagine, full generate/edit/extend +
  image-to-video + reference images (salvaged from PR #10600 by
  @Jaaneek, reshaped into the plugin interface)
- plugins/video_gen/fal/  — Veo 3.1 (t2v + i2v), Kling O3 i2v,
  Pixverse v6 i2v with model-aware payload building that drops keys a
  model doesn't declare

Wiring:
- agent/video_gen_provider.py — VideoGenProvider ABC, normalize_operation,
  success_response / error_response, save_b64_video / save_bytes_video,
  $HERMES_HOME/cache/videos/
- agent/video_gen_registry.py — thread-safe register/get/list +
  get_active_provider() reading video_gen.provider from config.yaml
- hermes_cli/plugins.py — PluginContext.register_video_gen_provider()
- hermes_cli/tools_config.py — Video Generation category in
  hermes tools, plugin-only providers list, model picker per plugin,
  config write to video_gen.{provider,model}
- toolsets.py — new video_gen toolset
- tests: 31 new tests covering ABC, registry, tool dispatch, both plugins
- docs: developer-guide/video-gen-provider-plugin.md (parallel to the
  image-gen guide), sidebar + toolsets-reference + plugin guides updated

Supersedes: #25035 (FAL), #17972 (FAL), #14543 (xAI), #13847 (HappyHorse),
#10458 (provider categories), #10786 (xAI media+search bundle), #2984
(FAL duplicate), #19086 (Google Veo standalone — easy port to plugin
interface).

* feat(video_gen): dynamic schema reflects active backend's capabilities

Address the 'capability variance' question — instead of one tool with a
static schema that lies about what every backend supports, the
video_generate tool now rebuilds its description at get_definitions()
time based on the configured video_gen.provider and video_gen.model.

The agent sees backend-specific guidance up-front:
- 'fal-ai/veo3.1/image-to-video': 'image-to-video only — image_url is
  REQUIRED; text-only prompts will be rejected'
- 'fal-ai/veo3.1' (t2v): no image_url restriction shown
- xAI grok-imagine-video: 'operations: generate, edit, extend; up to 7
  reference_image_urls'
- Backends without edit/extend: 'not supported on this backend — surface
  that they need to switch backends via hermes tools'

This is the same pattern PR #22694 used for delegate_task self-capping —
documented in the dynamic-tool-schemas skill. Cache invalidation is
free: get_tool_definitions() already memoizes on config.yaml mtime, so a
mid-session backend swap rebuilds the schema automatically.

Tested:
- Empirical FAL OpenAPI schema check confirms image-to-video models
  require image_url (FAL returns HTTP 422 otherwise) — client-side
  rejection in FALVideoGenProvider.generate() now prevents the wasted
  round-trip
- Live E2E: fal-ai/veo3.1/image-to-video + prompt-only → clean
  missing_image_url error; fal-ai/veo3.1 + prompt-only → dispatches
- 6 new tests cover the builder (no config / image-only / full-surface /
  text-only / unknown provider / registry wiring), all passing
- 37/37 in the slice, 134/134 in the broader regression set

* test(video_gen/xai): full surface integration tests + cleaner schema

Verified end-to-end that the xAI plugin handles every documented mode
from PR #10600's surface: text-to-video, image-to-video,
reference-images-to-video, video edit, video extend (with and without
prompt). All five modes route to the correct xAI endpoint
(/videos/generations, /videos/edits, /videos/extensions) with the right
payload shape (image / reference_images / video keys), and all five
client-side rejections fire before the network: edit-without-prompt,
extend-without-video_url, image+refs conflict, >7 references, and
duration/aspect_ratio clamping.

15 new integration tests grouped into four classes (endpoint routing,
modalities, validation, clamping). httpx is stubbed via a small fake
AsyncClient that records POSTs so the tests assert the actual payload
the plugin would send to xAI — not just the success/error envelope.

Also cleaned up a description redundancy: when a model's operations
match the backend's overall set, we no longer print the duplicate
'operations supported by this model' line. xAI's description now reads:

    Active backend: xAI . model: grok-imagine-video
    - operations supported by this backend: edit, extend, generate
    - modalities supported by this backend: image, reference_images, text
    - aspect_ratio choices: 16:9, 1:1, 2:3, 3:2, 3:4, 4:3, 9:16
    - resolution choices: 480p, 720p
    - duration range: 1-15s
    - reference_image_urls: up to 7 images

* feat(video_gen): collapse surface to t2v + i2v, family-based auto-routing

Two design changes per Teknium:

1) Drop edit/extend from the tool surface entirely. Only text-to-video
and image-to-video remain. The agent sees a clean tool with two
modalities; backend-specific quirks like xAI's edit/extend endpoints
stay out of the unified schema.

2) FAL: pick a model FAMILY once, the plugin routes between the
family's text-to-video and image-to-video endpoints based on whether
image_url was passed. Users no longer pick 'fal-ai/veo3.1' AND
'fal-ai/veo3.1/image-to-video' as separate options — they pick
'veo3.1', and the plugin handles the rest.

Catalog rewritten as families:

    veo3.1            fal-ai/veo3.1                                /  fal-ai/veo3.1/image-to-video
    pixverse-v6       fal-ai/pixverse/v6/text-to-video             /  fal-ai/pixverse/v6/image-to-video
    kling-o3-standard fal-ai/kling-video/o3/standard/text-to-video /  fal-ai/kling-video/o3/standard/image-to-video

xAI uses a single endpoint (/videos/generations) for both modes,
routed by the presence of the 'image' field in the payload — no
edit/extend exposure.

Schema changes:
- VIDEO_GENERATE_SCHEMA: drop operation, drop video_url. Final params:
  prompt (required), image_url, reference_image_urls, duration,
  aspect_ratio, resolution, negative_prompt, audio, seed, model.
- VideoGenProvider ABC: drop normalize_operation, VALID_OPERATIONS,
  DEFAULT_OPERATION. capabilities() drops 'operations' key.
- success_response: add 'modality' field ('text' | 'image') so the
  agent and logs can see which endpoint was actually hit.

Dynamic schema builder simplified — no operations bullet, no
'switch backends if you need edit/extend' guidance. When the active
backend supports both modalities (the common case), description reads:

    Active backend: FAL . model: pixverse-v6
    - supports both text-to-video (omit image_url) and image-to-video
      (pass image_url) - routes automatically
    - aspect_ratio choices: 16:9, 9:16, 1:1
    - resolution choices: 360p, 540p, 720p, 1080p
    - duration range: 1-15s
    - audio: pass audio=true to enable native audio (pricing tier)
    - negative_prompt: supported

Tests: 51 in the video_gen slice, 216 across the broader image+video
sweep, all passing. New FAL routing tests prove pixverse-v6 + no image
hits text-to-video endpoint, pixverse-v6 + image_url hits
image-to-video endpoint, same for veo3.1 and kling-o3-standard.

Docs updated: developer-guide page rewrites the 'model families' pattern
as a first-class section so external plugin authors know the convention.
toolsets-reference and toolsets.py descriptions match the new surface.

* feat(video_gen/fal): expand catalog to 6 families, cheap + premium tiers

Catalog now covers everything Teknium specced from FAL:

  Cheap tier:
    ltx-2.3        fal-ai/ltx-2.3-22b/text-to-video       / image-to-video
    pixverse-v6    fal-ai/pixverse/v6/text-to-video       / image-to-video

  Premium tier:
    veo3.1         fal-ai/veo3.1                          / fal-ai/veo3.1/image-to-video
    seedance-2.0   bytedance/seedance-2.0/text-to-video   / image-to-video
    kling-v3-4k    fal-ai/kling-video/v3/4k/text-to-video / image-to-video
    happy-horse    fal-ai/happy-horse/text-to-video       / image-to-video

DEFAULT_MODEL moved from veo3.1 (premium) to pixverse-v6 (cheap, sane
defaults, both modalities) — better first-run UX for users who haven't
explicitly picked a model.

New family-entry knob: image_param_key. Kling v3 4K's image-to-video
endpoint expects start_image_url instead of image_url; declaring
image_param_key='start_image_url' on the family lets _build_payload
remap correctly. Other families default to plain image_url.

Per-family capability flags reflect each model's docs:
- LTX 2.3 + Happy Horse: minimal payloads (no duration/aspect/resolution
  enum exposed by FAL — let endpoint apply defaults)
- Seedance: 6 aspect ratios incl 21:9, durations 4-15, audio supported,
  negative prompts NOT supported per docs
- Kling v3 4K: 16:9/9:16/1:1, 3-15s, audio + negative
- Veo 3.1: unchanged, 16:9/9:16, 4/6/8s

Tests: +5 covering the new families (full catalog, Kling 4K
start_image_url remap, Seedance routing, LTX payload minimality, Happy
Horse minimality). 56/56 in the slice green.

Note: I did NOT add the FAL-hosted xAI Grok-Imagine variant. Hermes
already has a direct xAI plugin that talks to xAI's own API; routing
the same model through FAL's wrapper would duplicate the surface
without adding capabilities. Users on FAL who want Grok-Imagine should
use the xAI plugin directly; flag if you want both routes available.

* test(video_gen): tool-surface routing matrix — every model x modality

End-to-end matrix test driven through _handle_video_generate() — the
actual function the agent's video_generate tool call lands in. Writes
config.yaml, invokes the registered handler with a raw args dict, then
asserts the outbound HTTP/SDK call hit the right endpoint with the right
payload shape.

Parametrized over FAL_FAMILIES.keys() so the matrix auto-discovers new
families as they're added (add a family to FAL_FAMILIES and you get
both modalities tested for free).

Coverage:
- All 6 FAL families x {text-only, text+image} = 12 cases
- xAI x {text-only, text+image} = 2 cases
- tool-level model= arg overrides config = 2 cases

For each case, verifies:
- result['success'] is True
- result['modality'] matches input shape ('text' if no image_url, 'image' otherwise)
- outbound endpoint URL matches the family's text_endpoint or image_endpoint
- text-only payloads carry no image-shaped keys
- text+image payloads carry the family's image key (image_url for most,
  start_image_url for kling-v3-4k, wrapped 'image' object for xAI)

All 16 cases passing. Confirms the tool surface routes every
(provider, model, modality) combination correctly with zero leakage.

* feat(video_gen): keep video_gen out of first-run setup, surface in status

Two changes:

1. video_gen joins _DEFAULT_OFF_TOOLSETS, so it is NOT pre-selected in
   the first-run toolset checklist. Video gen is niche, paid, and slow —
   most users don't want it nagging them during initial setup. Anyone
   who wants it opts in via 'hermes tools' -> Video Generation, which
   already routes to the provider+model picker.

2. The 'hermes setup' status panel learns about video_gen — but only
   shows the row when a plugin reports available. Users without
   FAL_KEY/XAI_API_KEY see nothing about video gen; users with one of
   those keys see 'Video Generation (FAL) ✓' as confirmation it's wired.

Verified live:
- Fresh install (no creds): zero video_gen mentions in wizard.
- With FAL_KEY: status row appears with active backend name.
- 160/160 in the setup + tools_config + video_gen test slice.

Rationale: image_gen is on by default because it's a featured creative
tool used in casual chat (telegrams, etc). Video gen is heavier — long
wait, paid per-second pricing. Default-off matches user intent better.
