Google does not publish gender for the 30 prebuilt Gemini voices —
inclusive design — but does publish a one-word style descriptor
(Bright, Firm, Smooth, Mature, Lively, etc.). Surface it so users can
pick by character.
- `audio.VoiceOption` gains `Labels map[string]string` (provider-
specific descriptors). ElevenLabs already returns labels via API;
Gemini now hardcodes `{"style": "..."}` per voice from the official
catalog.
- Web + desktop `mapCapVoiceToPortal` passes labels through. Both
pickers' `LABEL_KEYS` now include `"style"`, so the existing badge
rendering picks it up — first 1–2 entries shown next to the name.
- TS `VoiceOption` interface (web + desktop) gains optional `labels`.
No gender field is invented for Gemini voices.
