test(planning): complete test suite with Phase 11 edge cases
Implement comprehensive test infrastructure and all 124 tests across 11 phases: - Phase 0: Test infrastructure (fixtures, mocks, helpers) - Phases 1-10: Core planning engine tests (previously implemented) - Phase 11: Edge case omnibus (11 new tests) - Data edge cases: nil stadiums, malformed dates, invalid coordinates - Boundary conditions: driving limits, radius boundaries - Time zone cases: cross-timezone games, DST transitions Reorganize test structure under Planning/ directory with proper organization.
