CLAUDE: Add terminal client commands for manual outcome testing

New Commands:
- manual_outcome <outcome> [location] - Validates ManualOutcomeSubmission
  - Tests outcome and location validation
  - Shows which outcomes require hit location
  - Displays clear validation errors

- test_location <outcome> [handedness] [count] - Tests hit location distribution
  - Generates sample hit locations for an outcome
  - Shows distribution table with percentages
  - Validates pull rates (45% pull, 35% center, 20% opposite)
  - Supports both LHB and RHB

Implementation:
- Added validate_manual_outcome() to GameCommands class
- Added test_hit_location() to GameCommands class
- Added do_manual_outcome() to REPL
- Added do_test_location() to REPL
- Uses ManualOutcomeSubmission model from Task 3
- Uses calculate_hit_location() helper from Task 3

Testing:
- Tested manual_outcome with valid outcomes (groundball_c SS, strikeout)
- Tested manual_outcome with invalid outcome (proper error display)
- Tested test_location with groundball_c for RHB (shows distribution)
- All validation and display working correctly

Note: Full play resolution integration deferred to Week 7 Task 6 (WebSocket handlers).
      These commands validate and test the new models but don't resolve plays yet.
