feat: guarantee manual fallback and in-session draft recovery (#12)
Logging must never depend on AI availability, and an unsaved entry must not
disappear when the user navigates away mid-log.

- add src/vision-readiness.js so the photo flow consumes one readiness contract
- when the worker is offline/disabled/unknown, offer no AI action and no
  analysis-consent prompt, and keep manual Bristol entry one action away
- add src/draft.js and make the draft own the photo so a chosen photo and
  entered context survive a recoverable close or navigation, with a visible
  kept-draft summary and an explicit start over
- drafts stay in session memory only: a photo awaiting consent is never
  persisted, and reload starts clean
- service worker now refuses to cache image bodies in addition to analysis
  requests and no-store responses
- tests: 2 new unit files, 3 service-worker privacy assertions (1 hold-out),
  1 browser acceptance file, release-demo and CI/package assertions
- release demo now visibly replays the vision-offline pass and the retained
  draft with synthetic data and an in-script assertion
