feat: personality pack — Python parity

Python parity for the 5 personality voice commands shipped on the
Rust side:

- New `personality_handlers.py` (~150 lines): do_personality_{greet,
  thanks, compliment, how_are_you, tony_quote}. Each picks one of
  7-10 phrases per language (RU/EN) at random; greet additionally
  buckets by time-of-day (morning/midday/evening/night).
- `extensions.py`: imports + 5 proxy `do_personality_*` functions
  pointing at the new module, plus set_speak wiring so handlers can
  TTS via the runtime's voice.
- `main.py`: 5 new dispatch elifs feeding the new action types.
- `commands.yaml`: 5 new entries (`personality_*`) mapping voice
  phrases to action types.
- `tests/test_personality_handlers.py`: 6 unit tests confirming
  each handler returns a non-empty string from the expected pool.
- `.gitignore`: stop tracking runtime state generated by tests
  (profiles/, long_term_memory.json, schedule.json, macros.json,
  llm_backend.txt, llm_history.json) — these are user data, not
  source.

Tests: 54 → 60 (+6).
