This PR addresses the missing test coverage for three critical components of the BeamUp system by adding 40 new tests that bring the total test count from 37 to 77.

What's Added

🔄 correctionsOfProtocol unroll option tests

The correctionsOfProtocol function's unroll parameter was previously untested despite being a key feature for handling paginated API responses. This PR adds comprehensive tests covering:

// Test all unroll scenarios
await correctionsOfProtocol({ origin, protocol, unroll: false });    // No unrolling
await correctionsOfProtocol({ origin, protocol, unroll: 0 });        // Equivalent to false  
await correctionsOfProtocol({ origin, protocol, unroll: 2 });        // Limited to 2 requests
await correctionsOfProtocol({ origin, protocol, unroll: true });     // Infinite unrolling
await correctionsOfProtocol({ origin, protocol });                   // Default behavior

📄 src/pagination.ts tests

Created comprehensive test coverage for the pagination system including the paginated() function and PaginatedResponseSchema. Tests validate:

• Parameter parsing and validation (page, pagesize limits)
• Query parameter preservation in next_url generation
• Error handling for both Response instances and generic errors
• Empty results and edge cases
• Type safety with PaginatedResponse<T>

🌐 src/cors.ts tests

Added thorough testing for the CorsedResponse class that extends the standard Response to automatically inject CORS headers:

• Constructor behavior with various body types and custom init options
• Static methods (json(), redirect()) with automatic CORS header injection
• Environment variable integration (ALLOWED_ORIGINS)
• Header preservation when CORS headers already exist
• Multi-origin support and edge cases

Why This Matters

These components are fundamental to BeamUp's functionality:

• Pagination handles large datasets efficiently across the API
• CORS enables cross-origin requests for web clients
• Unroll option allows clients to fetch complete datasets vs. paginated chunks

The lack of test coverage made these features brittle and prone to regressions. With comprehensive tests in place, future changes can be made confidently.

Implementation Details

All tests follow existing patterns in the codebase:

• Use Bun's test framework consistently with describe/test structure
• Include both happy path and edge case scenarios
• Mock external dependencies appropriately
• Validate both success and error conditions
• Test environment variable behavior and configuration

The tests are isolated and don't interfere with existing functionality - all 77 tests pass with zero linting errors.
