feat(gateway): add LINE Messaging API platform plugin (#23197)
* feat(gateway): add LINE Messaging API platform plugin

Adds LINE as a bundled platform plugin under `plugins/platforms/line/`,
synthesized from the strongest pieces of seven open community PRs. The
adapter requires zero core edits — `Platform("line")` is auto-discovered
via the bundled-plugin scan in `gateway/config.py`, and all hooks
(setup, env-enablement, cron delivery, standalone send) are wired
through `register_platform()` kwargs the way IRC and Teams do it.

Highlights merged into one plugin:

- **Reply token preferred, Push fallback.** Try the free reply token
  first (single-use, ~60s TTL); fall back to metered Push when the
  token is absent, expired, or rejected. (PR #21023)
- **Slow-LLM Template Buttons postback.** When the LLM is still running
  past `LINE_SLOW_RESPONSE_THRESHOLD` (default 45s), the adapter burns
  the original reply token to send a "Get answer" button bubble. The
  user taps it to fetch the cached answer via a fresh reply token —
  also free. State machine: PENDING → READY → DELIVERED, ERROR for
  cancelled runs (orphan resolves to `LINE_INTERRUPTED_TEXT` after
  /stop). Set threshold to 0 to disable. (PR #18153)
- **Three-allowlist gating** — separate user / group / room allowlists
  with `LINE_ALLOW_ALL_USERS=true` dev-only escape hatch. (PR #18153)
- **Markdown URL preservation.** Strip bold/italic/code-fence/heading
  markers (LINE renders them literally) but keep `[label](url)` →
  `label (url)` so URLs stay tappable. (PR #18153)
- **System-message bypass** for ` Interrupting`, ` Queued`, etc. —
  busy-acks reach the user as visible bubbles instead of being
  swallowed into the postback cache. (PR #18153)
- **Media via public HTTPS URLs.** LINE doesn't accept binary uploads;
  images/audio/video must be HTTPS-reachable. The adapter serves
  registered tempfiles under `/line/media/<token>/<filename>` from the
  same aiohttp app. Allowed-roots traversal guard covers
  `tempfile.gettempdir()`, `/tmp` (→ `/private/tmp` on macOS), and
  `HERMES_HOME`. `LINE_PUBLIC_URL` overrides URL construction for
  setups behind tunnels/proxies. (PR #8398)
- **5-message-per-call batching.** LINE rejects >5 messages per
  Reply/Push; smart-chunker caps text at 4500 chars per bubble.
- **Inbound dedup** via `webhookEventId` LRU. (PR #21023)
- **Self-message filter** via `/v2/bot/info` userId lookup. (PR #21023)
- **Loading-animation indicator** wired to LINE's `chat/loading/start`
  endpoint, DM-only (LINE rejects it for groups/rooms). (PR #21023)
- **Out-of-process cron delivery** via `_standalone_send`, so
  `deliver: line` cron jobs work even when cron runs detached from
  the gateway.
- **Webhook hardening** — 1 MiB body cap, constant-time HMAC-SHA256
  signature verification, dedup, scoped lock so two profiles can't
  bind the same channel.

Validation
----------

- `scripts/run_tests.sh tests/gateway/test_line_plugin.py` →
  73 passed in 1.05s
- `scripts/run_tests.sh tests/gateway/test_line_plugin.py
  tests/gateway/test_irc_adapter.py
  tests/gateway/test_plugin_platform_interface.py
  tests/gateway/test_platform_registry.py
  tests/gateway/test_config.py` → 193 passed, 7 skipped
- E2E import + register + signature roundtrip + `Platform("line")`
  bundled-plugin discovery verified against current `origin/main`.

Closes the seven open LINE PRs (#18153, #16832, #6676, #21023, #14942,
#14988, #8398) by superseding them with a single plugin-form
implementation that takes the best idea from each.

* docs(platforms): document platform-specific slow-LLM UX pattern

Add a 'Platform-Specific Slow-LLM UX' section to the platform-adapter
developer guide covering the _keep_typing override pattern that LINE
uses for its Template Buttons postback flow.

Three subsections:
- Pattern: subclass _keep_typing to layer mid-flight UX (with code)
- Pattern: subclass send to route through a cache instead of sending
- When this pattern is appropriate (vs. always-Push fallback)

Plus a short pointer in gateway/platforms/ADDING_A_PLATFORM.md so
tree-readers find the prose walkthrough on the docsite.

Filed because the LINE plugin (PR #23197) was the first bundled
adapter to need this pattern — every prior plugin (irc, teams,
google_chat) handles slow responses with the default typing-loop and
a regular send_text. Documenting now while the rationale is fresh.
