Add bulk testing and export commands for modules

New Commands:
- tito module test [NUMBER]    - Test single module
- tito module test --all        - Test all 20 modules sequentially
- tito module complete --all    - Complete all modules (test + export)
- tito module reset --all       - Reset all modules (already existed)

Features:
- Detailed test results with pass/fail status
- --verbose flag for full test output
- --stop-on-fail to halt on first failure
- Summary table showing all module test results
- 5-minute timeout per module test
- Proper error reporting and exit codes

This enables:
- Quick validation of all modules after global changes
- Bulk export workflow for package releases
- Easy testing during development

+Module Test Command for TinyTorch CLI.
+
+Provides comprehensive module testing functionality:
+- Run individual module tests
+- Run all module tests in sequence
+- Display detailed test results
+- Track test failures and successes
+
+This enables students to verify their implementations are correct.
