* feat(desktop): add curated completion sound bank for turn completion
Replace the prior haptic-only completion cue with a curated Web Audio completion sound flow, defaulting to the minimal two-note comfort preset while keeping alternate presets available for quick iteration. Play the cue on every message completion event (including background sessions) so turn-end feedback is consistent across active and non-active chats.
* refactor(desktop): drop done1 byte sample from completion bank
Keep the curated Web Audio presets only; the embedded sample added bulk without shipping as the default cue.
* feat(desktop): expand completion sounds and add Appearance picker
Add fourteen synthesized turn-end presets with preview in settings, persisted variant selection, and softer default mixing for late-night use.

* refactor(desktop): dedupe completion-sound resolver, trim audio comments
Make the store the single source of truth for the variant default + range
validation and have the sound lib import it (one-way lib→store edge, no
cycle), instead of two divergent copies. Extract the shared white-noise
buffer used by the air/whoosh voices and cut the synth comments down to
why-only notes.
