- Added `providers.tinyModel` with an `online` default and UI schema metadata; documented tiny-title updates in changelogs.
- Added tiny-title system prompt and title-text helpers to truncate input, wrap `<user-message>`, and normalize output.
- Added tiny-title model registry, local model specs, key validation, and cache-path helper.
- Added tiny-title transport/client/worker flow with spawn fallback, queued requests, ping checks, and graceful close.
- Updated `generateSessionTitle` to route by tiny-title model and race local generation against delayed online fallback.
