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.** `magnotia-audio` has no Cargo features. `magnotia-transcription` has two: `whisper` (default on, gates `whisper-rs`, `whisper_rs_backend.rs`, and `load_whisper`) and `whisper-vulkan` (default on, additive Vulkan GPU offload). Parakeet is unconditional. The defaults give a desktop GPU build; non-Vulkan or cloud-only configurations turn features off explicitly.

 ## Build commands
 
 Default (Whisper + Vulkan):
 
 ```sh
-cargo build -p magnotia-transcription
+cargo build -p lumotia-transcription
 ```
 
 Whisper without Vulkan (CPU-only desktop, Android without GPU drivers):
 
 ```sh
-cargo build -p magnotia-transcription --no-default-features --features whisper
+cargo build -p lumotia-transcription --no-default-features --features whisper
 ```
 
 No Whisper at all (Parakeet only — useful for shrinking the binary and dropping `whisper-rs-sys`):
 
 ```sh
-cargo build -p magnotia-transcription --no-default-features
+cargo build -p lumotia-transcription --no-default-features
 ```
 
 The `--no-default-features` form drops the `whisper_rs_backend` module entirely, so any sibling code holding a `WhisperRsBackend` will fail to compile. `LocalEngine`, `SpeechModelAdapter`, `load_parakeet`, and the streaming primitives stay available.
