Add records, Elijah scores, per-session notes, and PWA update prompt

App features:
- Personal-best records per metric: manually settable in Settings and
  auto-updated when a session beats them; shown in the log modal and a
  new dashboard "Personal records" card.
- Juggling now counts by 1 instead of 5.
- 1-on-1 with Elijah gains Technical Skill and Effort scores (out of 10)
  as manual inputs, plus an optional per-session note.
- Service worker now uses a controlled update flow: an in-app
  "new version ready" banner activates the update on tap and reloads.

Data model:
- category_metrics gains track_record + record; entries gains note.
- Idempotent migrations bring existing databases up to date (juggling
  step/record, Elijah score metrics) alongside the updated seed.

StartOS package:
- Bump to 0.1.2:0 with release notes.
- Build x86_64 only (drop aarch64) per deployment target.
