feat(macros): IMBA-7 voice-recorded command sequences (VoiceAttack-style)

Simpler than AHK keyboard hooks: record what the user SAID, replay each phrase
through the normal dispatch path. Works for any command jarvis already knows.

Flow:
  "Запиши макрос работа"  → start_recording("работа")
  "Открой браузер"        → buffered into the recording
  "Запусти спотифай"      → buffered
  "Режим работа"          → buffered
  "Сохрани макрос"        → save_recording() → persist
  ...later...
  "Запусти макрос работа" → replay("работа") → fires each phrase in order

Core (crates/jarvis-core/src/macros.rs)
  - Macro {name, steps, created_at, last_run} persisted at
    <APP_CONFIG_DIR>/macros.json with atomic write-through.
  - Recording state in-memory: RwLock<Option<RecordingState>>.
  - start_recording / record_step / save_recording / cancel_recording.
  - list / get / delete / mark_run.
  - replay(name) spawns a thread that fires each step through a callback,
    with 800ms inter-step delay. Caller returns immediately.
  - is_macro_control filter prevents recording the meta-commands themselves
    (no infinite recursion when "запиши макрос" runs during a recording).
  - 3 unit tests (55 total).

Wiring (crates/jarvis-app/src/main.rs)
  - macros::init() before listener starts.
  - macros::set_replay_callback(move |phrase| text_cmd_tx.send(phrase)) — each
    replay step gets queued as a synthetic text command, processed by the same
    dispatcher the GUI uses. No special-case code path.

Recording hook (crates/jarvis-app/src/app.rs::execute_command)
  - On successful command execution → call macros::record_step(text).
  - Failed commands are NOT recorded (would fail on replay too).
  - is_macro_control filter inside record_step skips meta-commands.

Lua API (crates/jarvis-core/src/lua/api/macros.rs)
  - jarvis.macros.{start, save, cancel, replay, list, delete,
                   is_recording, recording_name}

Voice pack (resources/commands/macros/, 6 commands)
  - "запиши макрос NAME"       → macros.start_recording
  - "сохрани макрос"           → macros.save
  - "отмени макрос"            → macros.cancel
  - "запусти макрос NAME"      → macros.replay
  - "какие у меня макросы"     → macros.list
  - "удали макрос NAME"        → macros.delete

Build: cargo build --release -p jarvis-app green. 55/55 tests pass.
