Store readiness: in-app account deletion, privacy policy, terms, listing copy

Closes the remaining store-compliance gaps before App Store / Play
submission:

- Account deletion (App Store guideline 5.1.1): DELETE /me removes the
  user row (usage cascades). The app exposes it through one quiet
  'Account' caption link under the chat, visible only when signed in,
  driving two native dialogs (Sign out / Delete account with a
  destructive confirm) — no new views, no menus, minimalism intact.
  Deletion signs out and resets the app; copy notes that store
  subscriptions are cancelled in App Store / Play settings.
- docs/store/privacy-policy.md: the complete data inventory (matching
  the actual schema), transient OpenAI processing with no training, no
  profiling or ads, GDPR legal bases and rights, in-app erasure.
- docs/store/terms-of-service.md: not-therapy positioning with crisis
  guidance, AI-generated-content caveat, 18+ eligibility,
  auto-renewal/cancellation terms, liability, Swedish governing law.
- docs/store/listing.md: App Store and Play copy written to the
  honest-claims rule (subtitle 'Think Beyond Thought', keywords,
  descriptions), plus App Privacy and Data safety questionnaire
  mappings.
- LAUNCH.md updated: host the policy/terms, set store URLs, use the
  prepared listing copy.
- Tests: 30 passing (adds DELETE /me coverage).
