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.

 - **Tags**: `$lib/utils/frontmatter.js` exposes `deriveAutoTags` (currently returns `[]`), `buildFrontmatter`, `serialiseFrontmatter`, `buildMarkdown`. Manual tags stored as `item.manualTags`, rendered as removable chips in the expanded row with `+ add tag` input.

 ### Platform-aware window chrome (Linux fix)
 **Root cause:** Tauri v2 frameless `decorations: false` on KDE Wayland + webkit2gtk does not honour diagonal corner resize (collapses `NorthEast` etc. to a single axis via GTK's `gtk_window_begin_resize_drag`), and `data-tauri-drag-region` adds noticeable drag latency. Setting `setPointerCapture` ahead of `startResizeDragging` does not help once the compositor has taken over the pointer grab. Verified via Context7 docs + Codex diagnosis — Linux frameless is a known-fragile path.

 - Linux uses **native KWin/Mutter decorations**. `src-tauri/tauri.linux.conf.json` overlays `decorations: true` + full main window config (title, sizes) — overlays **replace** the windows array, so every field must be present, not just the delta. `src-tauri/src/commands/windows.rs` uses `cfg!(target_os = "linux")` to set decorations per window.
 - macOS / Windows keep custom chrome. `src/lib/utils/osInfo.js` `isLinux()` gates `<Titlebar>` and `<ResizeHandles>` via `useCustomChrome = $state(false)`; flips to `!isLinux()` after `loadOsInfo()` resolves.
 - Dueling drag-region handlers removed across Titlebar, float page, viewer page — everywhere a manual `startDragging()` lives, the `data-tauri-drag-region` attribute was deleted (they're alternatives per Tauri docs, not combinable).
-- `ResizeHandles` kept for macOS/Windows frameless: 12 px edges / 20 px corners via CSS vars (`--magnotia-resize-edge`, `--magnotia-resize-corner`), `pointerdown` + `setPointerCapture`, corners with explicit higher z-index. Handles rendered as siblings of the animated layout div so `position: fixed` is viewport-relative rather than captured by the transform containing block.

 ## What's deferred
 
 - **Transparent windows (`transparent: true`)** — Tauri issue #13270 reports this smooths drag/resize further on Linux, but it's moot now that Linux uses native decorations.
 - **File-system export (.md save dialog)** — currently clipboard-only. Needs a Rust `write_text_file` command for plugin-less file writes.
 - **Bulk select + bulk export** in History.
-- **LLM-powered content tags** (`topic:*`, `intent:*`) — slots into Task 7 `magnotia-llm` stub once Phase 3 wires real llama-cpp-2.
