fix: v2.7.4 — Changes matches JetBrains (#72), the chat says when Claude waits on a trust prompt (#73), Vietnamese Telex in Safari

- Changes (#72): a file git reports `MM` whose working copy equals HEAD again
  (a staged change since undone on disk) is no longer listed — JetBrains'
  GitChangesCollector drops it the same way. Mode-only changes stay listed.
  statusCounts (the dirty-tree safety checks) is unchanged.
- Chat (#73): Claude Code runs no hook before a folder is trusted, so a new
  pane's session has no row; the chat now says the session has not started,
  offers Open terminal, and asks before typing a message or /model //effort
  into the pane (an Enter would pick the trust prompt's "No, exit").
- Terminal: Safari + macOS's own Vietnamese Telex replaces the whole word on
  each key (insertReplacementText), which xterm.js ignores — only each word's
  first letter reached the pane. The edit is now sent as DELs + the new tail.
- Also: Ctrl+V pastes a screenshot into the terminal as a file path; the
  folder browser fallback lists files for a file field (`files=1`); the macOS
  native picker opens in front of the browser; a hidden tab is marked while a
  chat waits or once a turn ended; chat live line shows running calls, turn
  time and tokens, and "Done in …".
