agent: lumotia-rebrand — docs, scripts, root config, residuals

Phase 9 of the rebrand cascade. Sweep covers everything the Phase 8
frontend pass deliberately skipped: docs/, root markdown, scripts,
Cargo.toml descriptions, code comments that survived earlier
word-boundary sed, plus a handful of identifiers caught on the final
verify pass.

transcription-app changes:
- README.md, HANDOVER.md, KNOWN-ISSUES.md, run.sh — magnotia/Magnotia
  -> lumotia/Lumotia.
- docs/ — sweep across all subdirs except docs/handovers/ (preserved
  as immutable audit trail). Includes architecture-map references
  to magnotia_core::*, magnotia_storage::*, etc. now pointing at
  lumotia_*; dev-setup.md tracing output examples (lumotia_startup
  target); brief/ + superpowers/ + issues/ + whisper-ecosystem/ +
  audit/.
- Cargo.toml descriptions on 9 crates (core, audio, cloud-providers,
  hotkey, llm, mcp, plus referenced others).
- crates/core/src/{error,hardware,recommendation,paths}.rs +
  crates/audio/src/wav.rs + crates/llm/src/model_manager.rs +
  crates/cloud-providers/src/keystore.rs + crates/mcp/src/lib.rs —
  doc comments and a model-manager user-agent string.
- Caught on final pass: BroadcastChannel("magnotia_task_sync") -> ...
  ("lumotia_task_sync"); magnotia_locale i18n localStorage key
  renamed + migration shim added; CSS keyframe names
  magnotiaPulse / magnotiaBar / magnotiaFade renamed in the design-
  system kit; magnotia_viewer_item / magnotia_viewer_mode handoff
  keys renamed in HistoryPage + viewer/+page.svelte; src/assets/
  wordmark.svg text.
- src-tauri/src/lib.rs comment cleanup ("magnotia era" was sed'd
  to "lumotia era" earlier — restored).

Preserved (intentional):
- crates/core/src/paths.rs — keeps "magnotia" / "Magnotia" / ".magnotia"
  legacy detection strings in legacy_and_target_paths() so the
  migration shim can still find user data from the magnotia era.
- src/lib/stores/{page,focusTimer}.svelte.ts + src/lib/i18n/index.ts
  — migration call sites reference the legacy magnotia keys
  deliberately.
- docs/handovers/ — historical audit trail.

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

 | RB-01 | [c1-live-session-race.md](c1-live-session-race.md) | `src-tauri/commands/live.rs` | Added `LiveTranscriptionState.lifecycle: tokio::sync::Mutex<()>` and hold it across the async spans of both `start_live_transcription_session` and `stop_live_transcription_session`. The running-slot check/insert and stop/take/join sequence are now serialized, so concurrent starts can no longer both pass the empty-slot check and a start during stop blocks until the previous worker fully joins. Two async regression tests cover both races. |
 | RB-02 | [c3-migrations-atomicity.md](c3-migrations-atomicity.md) | `crates/storage/migrations.rs` | Each migration now runs inside a `pool.begin()` / `tx.commit()` transaction alongside its `schema_version` insert. Regression test injects a poisoned v9 migration and asserts neither the partial schema change nor the version row persists. DRY'd `run_migrations_up_to` test helper onto the same code path. |
 | RB-03 | [c4-transcript-profile-fk.md](c4-transcript-profile-fk.md) | `crates/storage/migrations.rs` + `database.rs` | Added a transactional v9 rebuild of `transcripts` that enforces `profile_id REFERENCES profiles(id) ON DELETE RESTRICT`, reassigns any orphaned transcript provenance to `DEFAULT_PROFILE_ID`, rebuilds dependent `segments` / FTS state, and preserves valid profile references. `insert_transcript` now rejects unknown profile ids up front, and `delete_profile` returns a clear reassign-first error when transcripts still reference the profile. Regression tests cover migration reconciliation, invalid inserts, and delete rejection. |
-| RB-04 | [run-live-session-monolith.md](run-live-session-monolith.md) | `src-tauri/commands/live.rs` | Replaced the 200+ line `run_live_session` loop with an explicit `LiveSessionRuntime` + `LiveLoopState` structure. Capture startup, runtime mic-error draining, audio chunk processing, overflow handling, stop-tail flush, inference dispatch/drain, and WAV finalisation each live in focused helpers, preserving behaviour while making the lifecycle auditable enough for RB-01 follow-up. Existing live tests and the full `magnotia` lib suite stay green. |

 | RB-05 | [poll-inference-channel-fatality.md](poll-inference-channel-fatality.md) | `src-tauri/commands/live.rs` | `poll_inference` now treats result-channel loss as a listener-lifecycle problem rather than a transcription failure. On the first `result_channel.send(...)` error it marks the live result listener as lost, emits a single warning that transcription will continue in the background, and keeps processing later chunks without retrying the dead channel. Regression test simulates a dead result listener and asserts chunk processing continues with only one warning. |
 | RB-06 | [native-capture-worker-join.md](native-capture-worker-join.md) | `src-tauri/commands/audio.rs` | `NativeCaptureState.stop_tx` replaced by `worker: AsyncMutex<Option<CaptureWorker>>`. `CaptureWorker` bundles the stop sender and the spawned task's `JoinHandle`; `stop_worker(worker)` sends stop then `await`s termination. Both `start_native_capture` (prior-worker stop) and `stop_native_capture` use the helper. Removed the 50ms sleep — the join barrier is exact. Two regression tests cover the lifecycle guarantee and the already-exited case. |
 | RB-07 | [runtime-capabilities-accelerators.md](runtime-capabilities-accelerators.md) | `src-tauri/commands/models.rs` | Introduced `compose_accelerators(whisper_enabled, loader_available, target)` as a pure helper; `supported_accelerators()` reads `cfg(feature = "whisper")`, `vulkan_loader_available()`, and target OS then delegates. `get_runtime_capabilities` uses it in place of the hard-coded `["cpu", "vulkan"]`. Whisper's `supports_gpu` now follows the feature flag. Five regression tests cover all permutations. |
