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.

 ## What shipped this session
 
 ### 9a — Export plumbing
-- `write_text_file_cmd` Rust command in new `src-tauri/src/commands/fs.rs`, with two unit tests (UTF-8 round-trip + bad-parent error path). Registered in `invoke_handler!`. `tempfile = "3"` added as `[dev-dependencies]` on the magnotia crate.
+- `write_text_file_cmd` Rust command in new `src-tauri/src/commands/fs.rs`, with two unit tests (UTF-8 round-trip + bad-parent error path). Registered in `invoke_handler!`. `tempfile = "3"` added as `[dev-dependencies]` on the lumotia crate.
 - `src/lib/utils/saveMarkdown.ts` utility centralises `suggestedFilename`, `saveTranscriptAsMarkdown`, `exportTranscriptsToDir` (directory-mode bulk export with in-batch collision suffixing).
 - HistoryPage `exportMarkdown` no longer copies to clipboard; it opens the OS save dialog and writes the file. Cancel returns silently.
 - HistoryPage gained a slim leading checkbox per row, a bulk-action toolbar (select-all / clear / export / delete), `Esc` to clear, `Cmd/Ctrl+A` to select-all-visible when focus is inside the list and not in a text input.
 
 ### 9b — LLM content tags
-- `magnotia-llm` exports a new `ContentTags { topic, intent }`, an `INTENT_CLOSED_SET`, an `is_valid_intent` helper, a `CONTENT_TAGS_SYSTEM` prompt and a `CONTENT_TAGS_GRAMMAR` GBNF (recursive style matching the existing `TASK_ARRAY_GRAMMAR`).
+- `lumotia-llm` exports a new `ContentTags { topic, intent }`, an `INTENT_CLOSED_SET`, an `is_valid_intent` helper, a `CONTENT_TAGS_SYSTEM` prompt and a `CONTENT_TAGS_GRAMMAR` GBNF (recursive style matching the existing `TASK_ARRAY_GRAMMAR`).
 - `LlmEngine::extract_content_tags` method follows the same render-chat → generate → JSON-parse shape as the existing `cleanup_text` and `extract_tasks`. Truncates to the trailing 2000 chars on a UTF-8 boundary; max_tokens 96 is enough for the JSON envelope. Smoke test in `crates/llm/tests/content_tags_smoke.rs` is gated on `MAGNOTIA_LLM_TEST_MODEL` matching the Phase 8 pattern.
 - `extract_content_tags_cmd` Tauri wrapper bridges through `state.llm_engine` with the standard `spawn_blocking` + `PowerAssertion` guard.
 
 ### 9b structural — migration v14 + persistence wiring
 A correction layered in after the critical-review pass discovered the original Task 9 was assuming a writable `saveHistory()` path that turned out to be a no-op stub.
 - Migration v14 adds `transcripts.llm_tags TEXT NOT NULL DEFAULT ''`.
-- `magnotia-storage` `database.rs` SELECT statements include the column. `TranscriptRow` + `transcript_row_from` carry it. `update_transcript_meta` accepts an `Option<&str>` for `llm_tags` (sixth optional, `#[allow(too_many_arguments)]` keeps clippy happy without inverting the signature into a struct).

 - `commands/transcripts.rs` `TranscriptDto` + `UpdateTranscriptMetaRequest` add `llm_tags`; `update_transcript_meta_cmd` forwards.
 - Frontend types: `TranscriptEntry.llmTags: string[]`, `TranscriptRow.llmTags: string`, `ContentTags`, optional `TranscriptMetaPatch.llmTags`.
 - `mapTranscriptRow` hydrates `llmTags`. `saveTranscriptMeta` now also forwards `llmTags` payloads. `buildFrontmatter` unions auto + manual + LLM tags into the exported markdown frontmatter.

 The original Phase 9 spec + plan committed at `49a795f` + `48d3db7` had three mismatches against the actual codebase, surfaced by a critical-review pass before execution. Layered as a corrections appendix in commit `3eb24f2`:
 
-1. `magnotia-llm` is `LlmEngine::generate(prompt, config)` synchronous, not the speculated `LlamaEngine::generate_chat(messages, config).await`.
+1. `lumotia-llm` is `LlmEngine::generate(prompt, config)` synchronous, not the speculated `LlamaEngine::generate_chat(messages, config).await`.
 2. `AppState.llm_engine: Arc<LlmEngine>` is direct, not behind a `RwLock`.
 3. **Structural** — `transcripts.llm_tags` requires a real SQLite migration plus Tauri command extension because the frontend `saveHistory()` is a no-op stub. Original plan assumed `manualTags`-mirroring would suffice. Migration v14 + `update_transcript_meta` extension landed as a new task to cover this. Picked up the latent `manualTags` persistence bug for free.

+1. **Manual dogfood walkthrough.** Cannot be driven by an automated agent. When opening Lumotia next:
    - Export one transcript via the History "Export .md" button — save dialog opens, file written to chosen path. Cancel — no toast, no fallback.
    - Select 3 history rows via checkboxes — toolbar surfaces, "Export selected" writes one .md per row to a chosen folder, collisions suffixed " (2)" etc.
    - Click "Tag" on one row — within a few seconds, dashed `topic:*` and `intent:*` chips appear. Click a chip — it moves into `manualTags` (solid accent chip). Page refresh — both `manualTags` and `llmTags` survive (this is the persistence-fix outcome).
