- Consolidate extractImageKey/extractFileKey/extractFileName into shared extractJSONStringField helper to reduce code duplication - Move mentionPlaceholderRegex to package-level position after imports - Rename feishuCfg field to config for clarity within FeishuChannel - Replace @_user_1 heuristic with GET /open-apis/bot/v3/info API call at startup for reliable bot @mention detection - Fix double close on file handle in downloadResource by removing defer and using explicit close in both success and error paths - Add unit tests for common.go and feishu_64.go helpers (53 test cases)
