- Fix Jalali/Gregorian/Hijri day-of-week startOffset formulas
(dow returns 0=Sat, not 0=Sun as the old comment claimed)
- Fix calendar and export month picker navigation jumping 2 months
(navMonth buttons already have pre-computed values; handlers
were decrementing/incrementing them again)
- Fix GetOrCreateUser/GetOrCreateDay race condition with INSERT OR IGNORE
- Add month/day bounds validation in handleEditMsg to prevent panic
- Hijri (قمری) calendar added as 3rd calendar option with tabular conversion
- Calendar type select menu (like accent) with gregorian/jalali/hijri
- Calendar type applied to exports and reports
- Midnight crossover: virtual splits at computation time (no synthetic DB events)
- Handles both UTC and local timezone boundaries
- Timezone changes handled naturally (recomputed on-the-fly)
- Rate limiting per user ID instead of chat ID
- WAL mode enabled for SQLite
- Smart reply keyboard updates after every state change
- Overlapping time edits rejected (must preserve in/out alternation)
- Single event deletion warns if timeline needs repair
- Day off no longer prevents clock in/out
- Accent colors shown with descriptive names in select menu
- Delete button label changed to DEL for visual distinction
- Add chat_id to events, settings, and days_off for per-user data
- Add proper graceful shutdown (signal handling, WaitGroup)
- Separate polling and webhook modes with goroutine management
- Add schema migration from single-user to multi-user schema
- Refactor handlers with shared actionFunc pattern (msg + callback)
- Fix schema path for Docker deployment (/app/db/schema.sql)
- Remove emoji from output text for cleaner formatting
