Regatta Timer v0.6

Closes #3.

Added

• Race persistence — start/sync/gun/reset persist on wall-clock
  timestamps; an in-flight countdown or race restores at the correct time
  after process death or reboot (12 h window; reset clears; gun-while-dead
  lands directly in count-up)
• Idle battery guard — armed screen hold releases silently after 10
  idle minutes; any tap re-arms (countdown always holds, bounded ≤5 min)
• State-aware tile — shows COUNTDOWN/RACING + Open when a timer is
  in flight instead of misleading arm chips
• Two-stage final count — light ticks 10–6, heavy clicks 5–1; the
  stage change marks "five to go"
• PRD.md behavior spec; privacy policy page; Play listing prep
  (playstore/); demo GIF/MP4 (amber count → gun → green race)

Changed

• Zone labels: slate blue → burgee gold (brand)
• Package renamed to com.johnhringiv.regattatimer (last chance before
  Play permanence)
• Site URLs → regatta-timer.johnhringiv.com; docs split into app/tile
  screenshot sections; Open Graph tags + share image

Infrastructure

• CI: actions bumped to Node-24 majors; Dependabot for actions; R8
  mapping attached to releases; docs-format (Prettier) check; release
  notes now sourced from the squash-commit changelog
• Repo: LF enforced via .gitattributes; Markdown pre-commit format hook;
  PR template encoding this changelog format; signed commits
