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.

-**Plain English summary.** `WhisperRsBackend` owns a `WhisperContext` from `whisper-rs` 0.16 and runs Whisper directly (not via `transcribe-rs`). It is the only backend that pipes Magnotia's `initial_prompt` into the model. Each call to `transcribe_sync` builds a fresh `WhisperState`, applies language and prompt parameters, picks a thread count via the power-aware helper, and converts segment timestamps from centiseconds to seconds before returning `Vec<Segment>`. Vulkan GPU offload is additive behind a Cargo feature.

 ## Watch-outs
 
 - **`whisper-rs-sys` is the C++ link target.** Brief item #6 documents the historical Whispering v7.11.0 failure linking `whisper-rs-sys` + `tokenizers` together on Windows MSVC. The `build.rs` guard panics if `tokenizers` ever lands in the workspace lockfile on a Windows target. See [build-tokenizers-guard.md](build-tokenizers-guard.md).
-- **Vulkan is detected at runtime, not just compile time.** `cfg!(feature = "whisper-vulkan")` is the static check; `vulkan_loader_available()` (slice 5 `magnotia_core::hardware`) confirms `libvulkan.so` actually resolves. If the feature is on but the loader is missing, the helper falls back to CPU thread count.

 - **Fresh state per call has a cost.** `state.full` warm-up is lower than `WhisperContext` load but non-zero. Brief comment hints reuse is possible. Worth measuring once the live-streaming path is dogfooded.
 - **No diarisation, no temperature fallback, no token suppression flags.** Greedy with `best_of: 1` is the simplest correct path. Tuning later is a single function.
 - **Timestamp units.** whisper-rs returns centiseconds (10 ms). Multiplying by `0.01` gives seconds. A prior version that used milliseconds or token offsets would slice timing wrong; tests should pin this.
