I'd like to work on this issue.

I have experience with Rust, Soroban contracts, and technical documentation. I'll add a clear Rustdoc comment for stream_count explaining exactly what is counted, including how cancelled and settled streams are handled, and ensure the documentation stays consistent with the contract's actual behavior.
