test(middleware): Add tests for CacheMiddleware and StartSessionMiddleware

[usernane]

File

Middleware/CacheMiddleware.php, Middleware/StartSessionMiddleware.php

Current Coverage

0% (0/41 combined)

Scenarios to Cover

• CacheMiddleware: caches response on first request
• CacheMiddleware: serves cached response on subsequent requests
• CacheMiddleware: cache invalidation / expiry
• CacheMiddleware: bypass cache for non-cacheable requests
• StartSessionMiddleware: session is started on before()
• StartSessionMiddleware: session is not re-started if already active

Notes

Both run on every matching request. Bugs here affect all users silently.
