LeftX 0ba71298e6 feat(feishu): support stream output (cardkit) (#2382)
* feat(feishu): add streaming support via CardKit PATCH API

Implement send_delta() for Feishu channel using interactive card
progressive editing:
- First delta creates a card with markdown content and typing cursor
- Subsequent deltas throttled at 0.5s to respect 5 QPS PATCH limit
- stream_end finalizes with full formatted card (tables, rich markdown)

Also refactors _send_message_sync to return message_id (str | None)
and adds _patch_card_sync for card updates.

Includes 17 new unit tests covering streaming lifecycle, config,
card building, and edge cases.

Made-with: Cursor

* feat(feishu): close CardKit streaming_mode on stream end

Call cardkit card.settings after final content update so chat preview
leaves default [生成中...] summary (Feishu streaming docs).
