feat: reactive character scheduling via self-rescheduling CharacterBatchJob

[herpaderpaldent]

Summary

Replaces fixed 1-minute cron polling with a self-perpetuating queue cycle. Once a character batch starts, it automatically re-schedules itself after REFRESH_DELAY_MINUTES (5 minutes), keeping characters continuously fresh without hammering the scheduler.

Changes

CharacterBatchJob

• Add REFRESH_DELAY_MINUTES = 5 constant
• Add $reschedule constructor param (default false) — controls whether finally() re-dispatches
• Store the originating queue name on BatchUpdate so re-dispatched jobs stay on the same queue
• shouldDiscardUpdate() simplified: only discards if the batch is still is_pending (the hour-window guard was appropriate for fixed polling, not needed with self-scheduling + ShouldBeUnique)

UpdateCharacter (bootstrap/catchup job)

• Rewritten to only dispatch CharacterBatchJob (with reschedule: true) for characters that:
  • Have never been updated, OR
  • Whose last batch finished > 10 minutes ago (stale/fallen-off)
• 2-second stagger delay per character to spread initial queue load
• Schedule changed from * * * * * → */30 * * * * (catchup only, not primary driver)

Migrations

• add_queue_to_batch_updates_table — new nullable queue column on batch_updates
• update_character_schedule_to_catchup — updates UpdateCharacter cron to */30 * * * *

Tests

All 13 targeted tests pass; full 564-test suite passes; PHPStan clean.

PR Summary

• Upgraded Storing Process fer Unfinished Jobs: We've baked a change into the system that adds a new spot fer awaiting orders in the 'batch_updates' ledger, so our friendly jobs aren't lost in the ether.
• Restructured Timing fer UpdateCharacter Work Orders: Our automated mate 'UpdateCharacter' will now be takin' a breather, his orders now come every 30 mins, not every minute. Less bother fer our crew, more efficient.
• Introduced a Mini-Timeout Variable: We've named a constant timer, 'REFRESH_DELAY_MINUTES' - a short 5 min break fer our engine room, the 'CharacterBatchJob' class. Gives us space to breathe.
• Updated Construction o' CharacterBatchJob: This creation process now comes with the option of a 'reschedule' flag. More control, more power, (insert mad laughter)!
• Revamped Job Execution Strategy: We've made it so our job dispenser can hold off some jobs if the new 'reschedule' flag is flyin'. Just making things smarter, ye see?
• Simplified Logic fer Discarding Updates: We've also made choosing when to toss out updates less complicated. The 'shouldDiscardUpdate' method's been improved.
• Remembered the Queue in Batch Updates: The 'resetBatchUpdate' method will now remember where we left off before we reset. No more losing our place in line!
• Polished the UpdateCharacter Job Framework: The system that sends out jobs fer updating our folks has been cleaned up real good. Now works wonders with folks who've got no updates or old ones. Smooth sailing!
• Enlarged the Scope o' Test Scenarios: We've put together new test scenarios making sure update orders for characters are dispatched proper-like. This includes first-timers and old-timers, and checks if 'reschedule' flag is handled right. Making sure our ship sails true!
