fix: batch resolve 5 issues from Feishu bug tracker

- fix(desktop): Settings Agents/Skills page layout overflow at narrow widths
  Shift header grid breakpoint md→xl, summary cards sm→3col, add min-w-0/truncate

- fix(desktop): TabBar tab style — remove border-r separators, use bg-only active state
  Drop ::after indicator and inter-tab borders; active tab distinguished by surface bg

- feat(desktop): IM Adapters page — horizontal tabs with Feishu first, Telegram second
  Replace vertical stack with tablist; add ImTabButton with aria-selected + focus-visible

- fix(server): bundled IM session cwd resolves to / instead of selected project
  Root cause: preload.ts chdir(CALLER_DIR) inherits '/' from Tauri-spawned sidecar.
  Fix: pin CALLER_DIR and PWD to session workDir in conversationService spawn env.
  Add diagnostic logs at sessionService, ws/handler, and conversationService.

- fix(feishu): StreamingCard shows duplicate "thinking" indicators
  Merge static loading element into streaming_content; renderedText() controls state.

- test(adapters): add 5 ImageBlockWatcher edge-case unit tests (reset, relative path,
  multi-image chunk, malformed data URI)
