* feat(feishu): add allow_chat option to filter by group chat_id
Allow binding specific group chats to a project via the allow_chat config
option, so multiple projects can share one Feishu app while each only
responds to its designated groups. Private (P2P) chats are unaffected.

* feat(feishu): share WebSocket connection across projects with same app_id
When multiple projects use the same Feishu app_id, Feishu's server
load-balances messages across WebSocket connections, causing messages
to randomly reach the wrong project. This change deduplicates WebSocket
connections per app_id: the first platform creates the connection
(primary), subsequent platforms reuse it (secondary). All events
(messages, card actions, bot menu) are fanned out to every platform
in the group, letting each platform's own allow_chat/allow_from
filters decide what to process.

* feat(feishu): add group_only option to ignore P2P messages
When group_only=true, the platform skips private (P2P) messages,
useful for projects that should only operate in group chats.

* ci: retrigger after flaky opencode test failure
The unit-test failure was in agent/opencode (TempDir cleanup race),
unrelated to this PR's changes. Retriggering CI.

* fix(feishu): address review feedback on shared WS and allow_chat
1. Card action fan-out now checks allow_chat before processing, so
the wrong project no longer claims card interactions from other chats.
2. Lark webhook mode respects isPrimary — secondary platforms no longer
start their own webhook, preventing double-processing.
3. Primary Stop() warns when secondaries will lose their event source.
4. Document group_only option in config.example.toml.
5. Add unit tests for ws_shared.go (register/unregister/allPlatforms).
6. Move event handler creation after isPrimary check so secondaries
skip building unused handlers.
