fix(skills/comfyui): bug fixes, cloud parity, expanded coverage, examples, tests

The audit of v4.1 surfaced ~70 issues across the five scripts and three
reference docs — most user-visible (silent file overwrites, status-error
misclassified as success, X-API-Key leaked to S3 on /api/view redirect,
Cloud endpoints that 404 because they were renamed). v5.0.0 fixes those
and fills the gaps that previously forced users to write their own glue
(WebSocket monitoring, batch/sweep, img2img upload helper, dep auto-fix,
log fetch, health check, example workflows).

Critical fixes
- run_workflow.py: poll_status now checks status_str==error BEFORE
  completed:true, so a failed run no longer reports success
- run_workflow.py: download_output streams to disk via safe_path_join,
  preserves server subfolder structure (no silent overwrites), and
  retries with exponential backoff
- run_workflow.py: refuses to overwrite a link with a literal in
  inject_params (would silently break wiring)
- _common.py: _StripSensitiveOnRedirectSession (subclasses
  requests.Session.rebuild_auth) drops X-API-Key/Cookie on cross-host
  redirects — fixes a real key-leak path through Cloud's signed-URL
  download flow. Tested
- Cloud routing (verified live): /history → /history_v2,
  /models/<f> → /experiment/models/<f>, plus folder aliases for the
  unet ↔ diffusion_models and clip ↔ text_encoders rename
- check_deps.py: distinguishes 200/empty vs 404 folder_not_found vs
  403 free-tier; emits concrete fix_command per missing dep
- extract_schema.py: prompt vs negative_prompt determined by tracing
  KSampler.{positive,negative} connections (incl. through Reroute /
  Primitive nodes) instead of meta-title heuristic; symmetric
  duplicate-name resolution; cycle-safe trace_to_node
- hardware_check.py: multi-GPU pick-best, Apple variant detection,
  Rosetta detection, WSL2, ROCm --json, disk-space check, optional
  PyTorch probe; powershell preferred over deprecated wmic
- comfyui_setup.sh: prefers pipx → uvx → pip --user (with PEP-668
  fallback); idempotent — skips relaunch if server already up;
  configurable port/workspace; persistent log; SIGINT trap

New scripts
- run_batch.py — count or sweep (cartesian product), parallel up to
  cloud tier limit
- ws_monitor.py — real-time WebSocket viewer; saves preview frames
- auto_fix_deps.py — runs comfy node install / model download for
  whatever check_deps reports missing (with --dry-run)
- health_check.py — single command that runs the verification checklist
  (comfy-cli + server + checkpoints + optional smoke test that cancels
  itself to avoid burning compute)
- fetch_logs.py — pull traceback / status messages for a prompt_id

Coverage expansion
- Param patterns now cover Flux (BasicScheduler, BasicGuider,
  RandomNoise, ModelSamplingFlux), SD3, Wan/Hunyuan/LTX video,
  IPAdapter, rgthree, easy-use, AnimateDiff
- Embedding refs in CLIPTextEncode strings extracted as model deps
- ckpt_name / vae_name / lora_name / unet_name now controllable so
  workflows can be retargeted per run

Examples
- workflows/{sd15,sdxl,flux_dev}_txt2img.json
- workflows/sdxl_{img2img,inpaint}.json
- workflows/upscale_4x.json
- workflows/{animatediff_video,wan_video_t2v}.json + README

Tests
- 117 tests (105 unit + 8 cloud integration + 4 cross-host security)
- Cloud tests auto-skip without COMFY_CLOUD_API_KEY; verified end-to-end
  against live cloud API

Backwards compatibility
- All existing CLI flags continue to work; new behavior is opt-in
  (--ws, --input-image, --randomize-seed, --flat-output, etc.)

+# Example Workflows
+
+These are starter API-format workflows for the most common tasks. They're
+ready to run with `scripts/run_workflow.py` once you've installed (or have
+cloud access to) the listed models.
+
+| File | Purpose | Required models | Min VRAM |
+|------|---------|-----------------|----------|
+| `sd15_txt2img.json` | SD 1.5 text-to-image (512×512) | SD1.5 checkpoint, e.g. `v1-5-pruned-emaonly.safetensors` | 4 GB |
+| `sdxl_txt2img.json` | SDXL text-to-image (1024×1024) | `sd_xl_base_1.0.safetensors` | 8 GB |
+| `flux_dev_txt2img.json` | Flux Dev text-to-image (1024×1024) | `flux1-dev.safetensors`, `t5xxl_fp16.safetensors`, `clip_l.safetensors`, `ae.safetensors` | 24 GB (or use `flux1-dev-fp8`) |
+| `sdxl_img2img.json` | SDXL image-to-image | SDXL checkpoint | 8 GB |
+| `sdxl_inpaint.json` | SDXL inpainting (image + mask) | SDXL checkpoint | 8 GB |
+| `upscale_4x.json` | Standalone 4× ESRGAN upscale | `4x-UltraSharp.pth` (or any upscaler) | 4 GB |
+| `animatediff_video.json` | AnimateDiff text-to-video (16 frames) | SD1.5 checkpoint, `mm_sd_v15_v2.ckpt` motion module | 8 GB |
+| `wan_video_t2v.json` | Wan 2.x text-to-video (~33 frames) | `wan2.2_t2v_1.3B_fp16.safetensors`, `umt5_xxl_fp16.safetensors`, `wan_2.1_vae.safetensors` | 24 GB |
+
+## Quick start
+
+```bash
+# Run a workflow with prompt injection
+python3 ../scripts/run_workflow.py \
+  --workflow sdxl_txt2img.json \
+  --args '{"prompt": "majestic eagle in flight", "seed": 12345, "steps": 35}' \
+  --output-dir ./out
+
+# Img2img: upload an input image first via the script's helper
+python3 ../scripts/run_workflow.py \
+  --workflow sdxl_img2img.json \
+  --input-image image=./photo.png \
+  --args '{"prompt": "make it watercolor", "denoise": 0.6}' \
+  --output-dir ./out
+
+# Cloud (set API key once)
+export COMFY_CLOUD_API_KEY="comfyui-..."
+python3 ../scripts/run_workflow.py \
+  --workflow flux_dev_txt2img.json \
+  --args '{"prompt": "a fox in a misty forest"}' \
+  --host https://cloud.comfy.org \
+  --output-dir ./out
+
+# What can I tweak in this workflow?
+python3 ../scripts/extract_schema.py sdxl_txt2img.json --summary-only
+
+# Are all required models / nodes installed?
+python3 ../scripts/check_deps.py wan_video_t2v.json
+```
+
+## Notes
+
+- **Inpaint masks**: white pixels = "regenerate this region", black = preserve.
+  ComfyUI's `LoadImageMask` reads the **red channel** by default; export your
+  mask as a single-channel image or as a normal RGB where red==intensity.
+
+- **Denoise strength** in img2img: `0.0` = output identical to input,
+  `1.0` = ignore input entirely. Sweet spot is usually 0.4–0.7.
+
+- **Flux Dev** needs ~24 GB VRAM in its base form. The `flux1-dev-fp8.safetensors`
+  variant (already on Comfy Cloud) cuts that roughly in half.
+
+- **Video workflows** can take many minutes. The skill auto-detects video
+  output nodes and bumps the default timeout to 900s. Override with `--timeout 1800`.
+
+- These JSON files are deliberately **API format** (top-level keys are node IDs
+  with `class_type`), not editor format. To open them in ComfyUI's web UI for
+  visual editing, use `Workflow → Load (API Format)` or `Workflow → Open` and
+  follow the prompt.
+
+## Cloud vs local model names
+
+Comfy Cloud's preinstalled checkpoints sometimes have a `-fp16` suffix
+(`v1-5-pruned-emaonly-fp16.safetensors`) while the canonical local download
+keeps the original name (`v1-5-pruned-emaonly.safetensors`). The example
+workflows use the local-canonical names. When running on cloud, override with:
+
+```bash
+python3 ../scripts/run_workflow.py \
+  --workflow sd15_txt2img.json \
+  --args '{"ckpt_name": "v1-5-pruned-emaonly-fp16.safetensors", "prompt": "..."}' \
+  --host https://cloud.comfy.org
+```
+
+The `ckpt_name`, `vae_name`, `lora_name`, `unet_name`, etc. are all exposed
+as controllable parameters by `extract_schema.py` — discover what's installed
+with `comfy model list` (local) or `curl /api/experiment/models/checkpoints`
+(cloud).
