agent: lumotia-rebrand — localStorage keys + event channels migration

Phase 7 of the rebrand cascade. Persisted UI state + inter-window event
channels migrated from magnotia to lumotia naming, with one-shot
localStorage key migration so dogfooded UI state survives the rename.

src/lib/utils/localStorageMigration.ts (new):
- migrateLocalStorageKey(old, new): idempotent + crash-safe shim.
  - If new key exists, removes old (lumotia value is authoritative).
  - If only old exists, copies value to new key, removes old.
  - If neither, no-op.
- migrateLocalStorageKeys(pairs): batch wrapper.

src/lib/stores/page.svelte.ts:
- 4 key constants renamed to lumotia_settings / lumotia_profiles /
  lumotia_task_lists / lumotia_templates.
- BroadcastChannel name renamed to lumotia_task_lists.
- migrateLocalStorageKeys() called at module load before any read.

src/lib/stores/focusTimer.svelte.ts:
- STORAGE_KEY renamed to lumotia.focusTimer.v1.
- migrateLocalStorageKey() called at module load.

Event channels (magnotia: -> lumotia:) renamed across frontend + Rust:
- magnotia:toggle-recording (src/routes/+layout.svelte)
- magnotia:hotkey-pressed / -released (src-tauri/src/commands/hotkey.rs +
  consumers)
- magnotia:open-wind-down (src-tauri/src/tray.rs + consumer)
- magnotia:llm-download-progress (src-tauri/src/commands/llm.rs)
- magnotia:preferences-changed (src/lib/stores/preferences.svelte.ts +
  consumers)
- magnotia:start-timer (nudgeBus + dispatch sites)
- magnotia:focus-timer-{complete,cancelled} (focusTimer + nudgeBus)
- magnotia:microstep-generated (nudgeBus + dispatch sites)
- magnotia:step-completed (nudgeBus + dispatch sites)
- magnotia:task-{completed,uncompleted,deleted} (page.svelte.ts +
  nudgeBus + consumers)

Storage-event filters in src/routes/{float,viewer,preview}/+layout@.svelte
updated to filter on lumotia_settings.

User-facing toast strings still say "Magnotia" — deferred to Phase 8
(frontend strings).

npm run check: 0 errors / 0 warnings (3958 files).
cargo test --workspace: 339 pass / 0 fail.
