- ComputeDailyTotals: only assume working from dayStart when first event
is 'out' (cross-midnight session); otherwise start idle. Fixes inflated
work/break counts in reports, status, export, burnout, salary, and RPG.
- leagueToggleCallback: add settings back keyboard when RPG is disabled.
- webhook: add graceful HTTP server shutdown on context cancellation.
- Fix 'string(d)' int-to-rune conversion in rpg_test.go by using fmt.Sprintf
- Fix ComputeDailyTotals dayStart logic: initial state should be StateWorking
when dayStart > 0, correctly counting work from dayStart to first out event
- Update README project structure to reflect new domain/handler/repo layout
- Implement missing achievements: rpg_pioneer (on RPG enable) and
salary_setter (on first rate set)
- Add tryUnlockAchievement helper to Handler
