Note

Remove anti-replay signature tracking from RPC agent authentication middleware

Removes the signature reuse detection system from Authentication to align with the Node TS rpc-agent behavior. The SIGNATURE_REUSE_WINDOW constant, @@used_signatures cache, @@signatures_mutex, and cleanup_old_signatures method are all deleted. Validity is now determined solely by HMAC equality and timestamp freshness.

• Behavioral Change: repeated requests with the same timestamp and signature within the allowed time window are now accepted instead of rejected.

Changes since #311 opened

• Removed test coverage for signature cleanup and thread safety in authentication middleware [ae79ea2]
• Renamed test example description for concurrent request handling [ae79ea2]

I think you can remove also the following tests (in authentication_spec.rb)

- removes signatures older than ALLOWED_TIME_DIFF
- mutex protects shared state from race conditions
