feat: Wave 5 Python parity — outlook COM + time tracker

Outlook COM (`outlook_handlers.py`, agent):
- 4 handlers mirroring Rust pack: unread_count, latest, send_clipboard,
  summarize_inbox. Uses `win32com.client` with lazy import so the module
  loads even when pywin32 is missing — handlers degrade gracefully and
  speak a "Outlook недоступен" reply.
- `requirements.txt`: pywin32>=305 (optional).
- 7 unit tests mock `_outlook_session` via unittest.mock.

Time tracker (`time_tracker_handlers.py`, agent):
- 5 handlers: start, stop, today, week, reset. JSON store at
  `<here>/time_tracker.json`, atomic write-then-rename.
- Same shape as the Rust pack's `jarvis.state` blob: current_session_start
  + sessions[{start,end}]. Local-calendar today boundary.
- Full Russian pluralisation (час/часа/часов, минута/минуты/минут).
- 14 unit tests using the existing `isolated_state` fixture in conftest.py.

`extensions.py` + `main.py`: imports + 9 new proxy do_* functions + 9
new dispatch elifs. `commands.yaml`: 9 new entries.

Tests: 60 → 81 (+14 tracker + 7 outlook).
