feat(overlay): add loading OSD spinner and queue notifications until ren

- Show mpv OSD spinner from start-file until subminer-overlay-loading-ready; force-shown for visible-overlay startup regardless of osd_messages setting
- Gate non-macOS overlay visibility on content-ready so first subtitle line is immediately hoverable and clickable
- Queue startup notifications in main process until overlay window finishes loading; upsert progress cards by id to avoid cold-start floods
- Defer background warmups until after overlay runtime init so queued notifications can deliver promptly
- Preserve character dictionary checking/building/importing/ready phases as distinct history entries; route building and importing to system notifications when notificationType is both

- `mpv.pauseUntilOverlayReady` waits for tokenization warmup plus visible-overlay readiness before
releasing the mpv startup gate.
- Cold `--start --background --managed-playback` launches handle initial args before the deferred
Yomitan wait, so the tray and visible overlay shell can receive startup notifications while
tokenization and annotation warmups continue.
- Visible-overlay startup creates the tray and visible overlay shell before tokenization and
annotation warmups continue. Cold `--start --background --managed-playback` launches still handle
initial args before the deferred Yomitan wait.
- Overlay-routed startup notifications are queued in the main process until an overlay window has
finished loading. Progress notifications with the same id are upserted so spinner ticks do not
flood a cold-start overlay, while events with distinct history ids are retained for phase-level
history such as character dictionary checking/building/importing.
- The mpv plugin has a 30-second fallback for cold starts; app-side retry/release budgets match that
window so readiness can still arrive before fallback resumes playback.
- If mpv is already on a subtitle, SubMiner still prefers the resolved current subtitle payload and
