feat+test: pytest suite + Now Playing + World Clock + Daily Quote packs (154 commands)

Adds first formal test suite for Python fork — 42 tests covering memory_store,
profiles_store, scheduler_store, macros_store, llm_backend. All pass.

Tests (tests/, ~290 lines)
  conftest.py — `isolated_state` fixture: rewires _PATH/_PROFILES_DIR etc to
                a per-test tmp_path so concurrent runs don't touch real data.
  test_memory_store.py     — 9 tests: remember/recall/forget round-trip,
                              search by key/value, limit/empty query,
                              persistence across reload, build_llm_context
  test_profiles_store.py   — 7 tests: seeded defaults, set_active persistence,
                              allows_command logic (default/work/driving)
  test_scheduler_store.py  — 12 tests: parser (daily/at/every/in, ru units,
                              bad input), add/remove/clear/remove_by_text,
                              _next_fire for each schedule kind
  test_macros_store.py     — 8 tests: is_macro_control filter, start/save
                              round-trip, control-phrase filtering, list_names
                              sorted, replay unknown raises
  test_llm_backend.py      — 6 tests: parse_backend aliases (ru + en),
                              persist round-trip, auto-detect logic
