evanfang0054 da4114dfe3 feat(feishu): isolate Harness sessions per topic in topic groups ... conversationKey derived the group session key from chat_id alone, so in Feishu topic groups every topic shared one Harness session: context, /new, pending approvals, and batch-input state all leaked across topics. Append the event's thread_id to the session key when present. Topic groups stamp every message with a thread_id, so each topic now maps to its own group:<chat_id>🧵<thread_id> session. Regular group chats carry no thread_id and keep the single shared group:<chat_id> key; p2p keys are untouched. - message-utils.mjs: thread-aware conversationKey - message-utils.test.mjs: topic isolation + regular-group fallback cases - lib/index.js: regenerated host bundle		2026-08-31 13:54:35 +08:00
