feat(ux): dogfood pass — onboarding, tasks, LLM chip, float popout

Bundles a session of dogfood UX feedback plus the two Cursor Bugbot
findings on the auto-titles branch.

Onboarding (FirstRunPage):
- Welcome leads with "Set up automatically"; system breakdown and the
  full model list move behind a "Choose manually" disclosure
- Morning / evening / autostart modal copy trimmed to one short
  sentence each; CTAs shortened
- "Corbie" autostart string reverted to "Kon"
- Already-downloaded models are clickable in the picker so the
  Settings → About → Replay onboarding flow doesn't re-download
- Autostart "No thanks" now does isEnabled() → disable() to actually
  remove the OS login item when replaying after a previous "Yes"

Tasks page:
- Bucket nav (All / Inbox / Today / Soon / Later) now a horizontal
  pill row; was stacking because nav was block-level
- List sidebar sized to content via self-start max-h-full instead of
  stretching to viewport when sparse
- Energy chip surfaces at opacity-60 when unset (was opacity-0,
  hidden until hover) so the affordance is discoverable
- "Brain-Dead" energy label → "Zero" everywhere user-facing; enum
  stays brain_dead to avoid a destructive DB migration

LLM status chip (llmStatus.svelte.ts + Dictation/Settings):
- Chip no longer auto-warms when the engine isn't loaded; it's hidden
  unless ready / generating / loading / error
- refreshLlmStatus takes { force: true } so post-load reconcile clears
  stale "warming"; ambient refreshes still preserve in-flight state
- markError exported; failed loads surface "AI error" with detail
  rather than silently going to off
- check_llm_model is the source of truth (replaces the bool-only
  get_llm_status path in the store)

Float popout window:
- Native decorations off — was stacking two titlebars + two close X's
  on KWin, one of which silently failed
- ResizeHandles mounted outside the animate-float-enter wrapper so
  fixed-position handles anchor to the viewport, not the transformed
  root; secondary-windows capability gains
  core:window:allow-start-resize-dragging for tasks-float
- GTK Utility WindowTypeHint applied pre-map (mirroring the preview
  window) so KWin Wayland honours always-on-top reliably
- visible_on_all_workspaces(true) so the pinned tasks list follows
  workspace switches
- togglePin does hide()+show()+focus() on re-pin to nudge the
  compositor into re-evaluating window state
- Pop-out / Edit / Open viewer buttons hidden on Android via
  isAndroid() — the multi-window Tauri commands stub out there

Build / Bugbot:
- src-tauri Cargo.toml: whisper feature now chains whisper-vulkan, so
  the dev runner's --no-default-features --features whisper
  invocation actually pulls Vulkan acceleration instead of silently
  falling back to CPU-only
- jsconfig.json's inherited "types": ["node"] fixed by adding
  @types/node; corresponding @ts-expect-error in vite.config.js
  removed now that process is a known global

Verification: svelte-check + cargo check pass clean. Manual
device-side validation still pending for float resize and replay
autostart "No thanks" — those are the only remaining confidence items.
