feat(channels): add Feishu (Lark) channel adapter (#4379)
* feat(channels): add Feishu (Lark) channel adapter

* fix(channels/feishu): fix webhook stop button, memory leak, spin-wait timeout, and reaction cleanup

* fix(channels/feishu): fix security, stability and build issues from PR review

* fix(channels/feishu): fix card lifecycle, streaming limits, and download safety from CR round 2

* fix(channels/feishu): harden webhook, card lifecycle, and disconnect cleanup from CR round 3

* fix(feishu): clarify stoppedMessages JSDoc to match actual cleanup behavior

* fix(channels/feishu): handle post messages without language key wrapper in quote context

* fix(channels/feishu): fix webhook signature bypass, stop-button double-send, and blockStreaming duplicates from CR round 4

* fix(channels/feishu): harden card lifecycle, markdown splitting, and defensive guards from CR round 5

* fix(channels/feishu): harden card lifecycle, markdown splitting, and defensive guards from CR round 5

- Set cardCreationFailed on onPromptStart failure to prevent retry spiral
- Skip throttle updates when card creation permanently failed
- Handle code fences in hard-split and table-stripping fallbacks
- Use parity-based fence detection in splitByTables (align with splitChunks)
- Add cs.stopped and else branch in onPromptEnd to prevent timer race and state leak
- Mark cardState.stopped after busy-wait timeout to abandon orphaned in-flight creation
- Apply MAX_CARD_CHARS truncation with fence parity in onResponseComplete
- Sanitize senderId before <at> tag interpolation
- Use replaceAll + callback form for mention replacement
- Floor token expiry to prevent thundering herd on expire:0
- Add log for stop-button auth rejection
- Fix stoppedMessages JSDoc to match actual cleanup lifecycle
- Fix test fixture to match "still creating" scenario
- Fix typecheck errors in test file (TS2571, TS4111)
- Add stop-button auth negative path tests (operator mismatch, missing operator, missing sender)
- Replace spanning regex in table-stripping with line-by-line stripTables() to resolve CodeQL ReDoS warning

* fix(channels/feishu): fix HMAC bypass, prompt injection, SSRF, and card lifecycle from CR round 5-6

Security:
- Fix webhook HMAC bypass: use defineProperty(non-enumerable) for headers instead of prototype shadowing
- Fix cross-user prompt injection: mark quoted content as untrusted with explicit marker
- Fix SSRF: validate all Feishu IDs with FEISHU_ID_RE before URL interpolation in 6 endpoints
- Fix safeSenderId regex: add hyphen to character class so ou_abc-def-123 is not rejected

Card lifecycle:
- Set cardCreationFailed on onPromptStart failure to prevent retry spiral
- Skip throttle updates when card creation permanently failed
- Fallback to plain message delivery when cardCreationFailed with accumulated text
- Track creationTimer in CardSessionState so cleanupCard/disconnect can cancel orphaned card creation
- Add cs.stopped and else branch in onPromptEnd to prevent timer race and state leak
- Mark cardState.stopped after busy-wait timeout to abandon orphaned in-flight creation
- Apply MAX_CARD_CHARS truncation with fence parity in onResponseComplete
- Preserve atPrefix in streaming truncation to prevent @mention visual snap
- Account for suffix and fence reserve in truncation maxBody calculation
- Clean up auxiliary maps after handleInbound when gate rejects the message
- Clean up blockStreaming mode Map entries in onPromptEnd
- Skip bare @mention without question text

Markdown:
- Handle code fences in hard-split and table-stripping fallbacks
- Use parity-based fence detection in splitByTables (align with splitChunks)
- Replace spanning regex in table-stripping with line-by-line stripTables() to resolve CodeQL ReDoS warning

Defensive guards:
- Sanitize senderId before <at> tag interpolation
- Use replaceAll + callback form for mention replacement
- Floor token expiry to prevent thundering herd on expire:0
- Add log for stop-button auth rejection

Tests:
- Fix stoppedMessages JSDoc to match actual cleanup lifecycle
- Fix test fixture to match "still creating" scenario
- Fix typecheck errors in test file (TS2571, TS4111)
- Add stop-button auth negative path tests (operator mismatch, missing operator, missing sender)
- Assert cancelSession called in stop-button happy-path test

* fix(channels/feishu): add request timeouts, token dedup, and harden file/quote sanitization

* fix(channels/feishu): harden card lifecycle, webhook auth, and resource cleanup from CR round 7

* fix(channels/feishu): harden card lifecycle, mention handling, and error recovery
