test(planning): complete test suite with Phase 11 edge cases

Browse Source 
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.

# Test Suite Implementation Plan
**Scope:** TO-DOS items 20.0 - 20.10
**Approach:** TDD — tests define expected behavior, then app code is updated to pass
**Framework:** Swift Testing (`@Test`, `#expect`, `@Suite`) with XCTest fallback if needed
**Status:** Use checkboxes to track progress
---
## Pre-Implementation Setup
### Phase 0: Test Infrastructure
> Set up foundations before writing any feature tests.
- [x] **0.1** Create `SportsTimeTests/` directory structure:
```
SportsTimeTests/
├── Fixtures/
│ └── FixtureGenerator.swift
├── Mocks/
│ ├── MockCloudKitService.swift
│ ├── MockLocationService.swift
│ └── MockAppDataProvider.swift
├── Helpers/
│ ├── BruteForceRouteVerifier.swift
│ └── TestConstants.swift
├── Planning/
│ ├── GameDAGRouterTests.swift
│ ├── ScenarioAPlannerTests.swift
│ ├── ScenarioBPlannerTests.swift
│ ├── ScenarioCPlannerTests.swift
│ ├── TravelEstimatorTests.swift
│ ├── ItineraryBuilderTests.swift
│ └── TripPlanningEngineTests.swift
└── Performance/
└── PlannerScaleTests.swift
```
- [x] **0.2** Implement `FixtureGenerator.swift`:
- Generate synthetic `Game` objects with configurable:
- Count (5, 50, 500, 2000, 10000)
- Date range
- Geographic spread
- Stadium/team distribution
- Generate synthetic `Stadium` dictionary
- Generate synthetic `Trip` with configurable stops
- Deterministic seeding for reproducible tests
- [x] **0.3** Implement `MockCloudKitService.swift`:
- Stub all public methods
- Return fixture data
- Configurable error injection
- [x] **0.4** Implement `MockLocationService.swift`:
- Stub geocoding
- Stub routing (return pre-calculated distances)
- Configurable latency simulation
- [x] **0.5** Implement `MockAppDataProvider.swift`:
- Return fixture stadiums/teams/games
- Configurable to simulate empty data
- [x] **0.6** Implement `BruteForceRouteVerifier.swift`:
- For inputs with ≤8 stops, exhaustively enumerate all permutations
- Compare engine result against true optimal
- Used to validate "no obviously better route exists"
- [x] **0.7** Implement `TestConstants.swift`:
```swift
enum TestConstants {
static let nearbyRadiusMiles: Double = 50.0
static let performanceTimeout: TimeInterval = 300.0 // 5 min
static let hangTimeout: TimeInterval = 30.0
// Baselines TBD after initial runs
static var baseline500Games: TimeInterval = 0
static var baseline2000Games: TimeInterval = 0
static var baseline10000Games: TimeInterval = 0
}
```

## API Proposals (TDD Discoveries)
These APIs will be defined by tests and need implementation:
| Property/Type | Defined In | Description |
|--------------|------------|-------------|
| `Trip.warnings: [PlanningWarning]` | 2.13 | Warnings when planner overrides preferences |
| `PlanningWarning` enum | 2.13 | `.repeatCityOverridden(city: String)`, etc. |
| `PlanningError.noGamesFound` | 4.4 | Thrown when date range has no games |
| `Trip.status: TripStatus` | 9.5 | `.planned`, `.inProgress`, `.completed` |
---
## Execution Order
**Recommended batch order for TDD cycle:**
1. **Phase 0** — Infrastructure (no app changes)
2. **Phase 1** — TravelEstimator (foundation, likely passes)
3. **Phase 2** — GameDAGRouter core (highest risk, most edge cases)
4. **Phase 3** — GameDAGRouter scale (set baselines)
5. **Phase 4-6** — Scenario planners (A, B, C)
6. **Phase 7** — TripPlanningEngine integration
7. **Phase 8** — ItineraryBuilder
8. **Phase 9** — RouteFilters
9. **Phase 10** — Concurrency (documentation tests)
10. **Phase 11** — Edge cases

## Notes
- **Hang timeout:** 30 seconds (tests marked as hanging if exceeded)
- **Performance timeout:** 5 minutes per test (scale tests)
- **Nearby radius:** 50 miles driving distance (`TestConstants.nearbyRadiusMiles`)
- **Brute force threshold:** ≤8 stops for exact optimality verification
- **Baselines:** Will be recorded after initial runs, then hardcoded
