Add a request logging middleware to the core server that records every API call (method, path, status, duration, timestamp). Expose the log via GET /_emulate/requests and DELETE /_emulate/requests endpoints, plus requests() and clearRequests() methods on the Emulator interface. Uses a ring buffer of 1000 entries to bound memory. Requests to /_emulate/* control endpoints are excluded from the log. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
Add request logging middleware that records every API call to an emulated service. Each request is logged with method, path, status code, duration, and timestamp. The log is accessible via
emulator.requests()in the programmatic API andGET /_emulate/requestsover HTTP.Why this matters
When an integration test fails against emulate, there is currently no way to see what requests hit the emulated service or what responses were returned. Mockoon and MSW both provide request introspection. This is essential for debugging test failures, especially when running multiple services.
Changes
packages/@emulators/core/src/server.ts: Added request logging middleware (ring buffer, 1000 entries max) and/_emulate/requestsendpoints (GET to read, DELETE to clear).
