fix: patch connection.destroy (mysql)

[sohankshirsagar]

Note

Wraps Connection.prototype.destroy (no-op in REPLAY) and adds E2E endpoint/tests to exercise destroy, updating run scripts accordingly.

• Instrumentation (mysql):
  • Wraps Connection.prototype.destroy via _getDestroyPatchFn(); no-op in REPLAY, passthrough in RECORD/DISABLED.
• E2E tests:
  • Adds GET /test/connection-destroy endpoint in cjs-mysql/src/index.ts and esm-mysql/src/index.ts to validate destroy() behavior.
  • Updates cjs-mysql/run.sh and esm-mysql/run.sh to call the new endpoint; enables cleanup_tusk_files in ESM script.
• Misc:
  • Minor string/style consistency updates in test servers.
