Trey T db6ab2f923 Implement 4-phase improvement plan with TDD verification + travel integrity tests ...

- Phase 1: Verify broken filter fixes (route preference, region filtering,
  must-stop, segment validation) — all already implemented, 8 TDD tests added
- Phase 2: Verify guard rails (no fallback distance, same-stadium gap,
  overnight rest, exclusion warnings) — all implemented, 12 TDD tests added
- Phase 3: Fix 2 timezone edge case tests (use fixed ET calendar), verify
  driving constraints, filter cascades, anchors, interactions — 5 tests added
- Phase 4: Add sortByRoutePreference() for post-planning re-sort, verify
  inverted date range rejection, empty sports warning, region boundaries — 8 tests
- Travel Integrity: 32 tests verifying N stops → N-1 segments invariant
  across all 5 scenario planners, ItineraryBuilder, isValid, and engine gate

New: sortByRoutePreference() on ItineraryOption (Direct/Scenic/Balanced)
Fixed: TimezoneEdgeCaseTests now timezone-independent

1199 tests, 0 failures.
