feat: memory v2, prompt styles, Dream/GAZE integration, Wyoming TTS fix

SQLite + sqlite-vec replaces JSON memory files with semantic search,
follow-up injection, privacy levels, and lifecycle management.

Six prompt styles (quick/standard/creative/roleplayer/game-master/storyteller)
with per-style Claude model tiering (Haiku/Sonnet/Opus), temperature control,
and section stripping. Characters can set default style and per-style overrides.

Dream character import and GAZE character linking in the dashboard editor
with auto-populated fields, cover image resolution, and preset assignment.

Bridge: session isolation (conversation_id / 12h satellite buckets),
model routing refactor, PUT/DELETE support, memory REST endpoints.

Dashboard: mobile-responsive sidebar, retry button, style picker in chat,
follow-up banner, memory lifecycle/privacy UI, cloud model options in editor.

Wyoming TTS: upgraded to v1.8.0 for HA 1.7.2 compatibility.
