feat: add contact search to command bar (Spotlight-style)

Transform the command bar from a simple phone dialer into a full
contact search bar. Users can now type a name to search the phonebook
and local operators, navigate results with arrow keys, and call with
Enter.

- Search phonebook via API with 250ms debounce and stale-request
  cancellation
- Local operator matching (name + extension) displayed first, deduped
  against phonebook results
- Operator results show avatar and presence indicator
- Keyboard navigation: ArrowUp/Down to select, Enter to call, Escape
  to close
- Dynamic window resize via new COMMAND_BAR_RESIZE IPC event with full
  setBounds rect (avoids DPI issues on Windows)
- Cache operators/avatars with 30s TTL to avoid redundant API calls
- Memoize expensive computations (operator filtering, result merging)
- Fix IPC listener leak: proper cleanup on effect re-run
- Non-mutating mapContact for safer data handling
