AI Summary: This issue addresses a memory leak in the in-memory rate limiter where expired window entries are replaced on access but never deleted from the `Map`. The proposed fix is to implement a `setInterval` that periodically sweeps the map (every `windowMs`) and removes entries that have expired, preventing unbounded memory growth.

AI Summary: The client's `claimBounty` API request unnecessarily sends a `nodeId` in its request body. The server does not utilize this `nodeId` from the body, instead deriving it from authentication (Bearer token or API key). The issue proposes removing this redundant `nodeId` from the client's request.
