Beta release version 0.5.1

· Explicit daily schedule replaces rotation + holiday system — daily-schedule.json maps specific dates to puzzle IDs with optional holiday metadata

· Daily puzzle pools moved to packs.json — weekdayPuzzleIDs and weekendPuzzleIDs fields for fallback rotation

· Shared puzzle link is now tappable for recipients — deep link opens the puzzle directly

· Fixed: share sheet opens blank on first tap

· Fixed: release-drafter PR trigger restricted to main branch only

The following should be verified before shipping this release:

· Verify daily puzzle matches the entry in daily-schedule.json for today's date

· Verify fallback to weekday/weekend rotation pools when date is not in schedule

· Verify daily-schedule.json with holiday metadata renders holiday badge on DailyPuzzleCard

· Verify daily-schedule.json with null holiday shows no holiday badge

· Verify shared puzzle link opens the correct puzzle when tapped by a recipient

· Verify share sheet opens with content on the first tap (no blank sheet)

· Verify packs.json weekdayPuzzleIDs and weekendPuzzleIDs are populated correctly

· Verify release-drafter only triggers on PRs to main (not develop)

· Run full unit test suite (LamplitTests) — all tests pass

The following features are planned but not included in this release:

· Phase 2.3 — Ambient audio loop (crackling fire / rain) — deferred due to licensing
