feat/annual schedule - #16
Conversation
Calculate annual crons from the next real occurrence so DST offsets match the target year. Guard timezone-shifted leap-day runs against firing in non-leap years.
📝 WalkthroughWalkthroughThe PR adds yearly scheduling with month, day, and time configuration. It validates calendar dates, creates timezone-aware cron schedules, executes yearly tasks, persists settings in backups, and updates forms, documentation, and tests. ChangesYearly scheduling
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to Yearly schedules can run at the wrong local time when their configured time falls inside a spring-forward DST gap; this should be fixed or explicitly accepted by the owner before merging.

so it covers the next valid Gregorian leap-day occurrence after February 29,
2096, including skipping non-leap year 2100; preserve the existing candidate
validation and return behavior. Add a regression test using a time after
February 29, 2096 that verifies February 29, 2104 is selected instead of
returning None.

Extend the yearly search horizon so 29 February schedules find 2104 after the non-leap year 2100.

Summary
Adds yearly bot schedules with a single month, day, time, and timezone.
Yearly schedules calculate the next real local occurrence before generating the UTC cron, including DST and year-boundary adjustments.
February 29 schedules run only in leap years, including when timezone conversion shifts the UTC date to February 28 or March 1.
Also adds plugin API support, backup/restore fields, UI validation, documentation, migration, and tests.

Notes for reviewers
February 29 executes only in leap years; there is no “last day of February” fallback.
Timezone-shifted leap-day crons use a local-date guard to prevent execution in non-leap years.
ScheduleAPI.sync() accepts mode="yearly" with month, day, time_str, and tz.
Backup format was bumped from 1.7.0 to 1.8.0.
Migration 0054_yearly_schedule adds the yearly scheduling fields.
python manage.py check, migration consistency checks, 11 yearly tests, and 64 related scheduling/API tests passed.
The complete core suite was attempted but encountered existing environment failures involving the missing staticfiles manifest and sandbox
execution through the temporary Python environment.
SQLite migration coverage passed through Django tests; PostgreSQL migration coverage was not run locally.
