Rustdocs missing for some core items

[Evian-Zhang]

Describe the bug
Some items are core in MCP server development, like rmcp::transport::streamable_http_server::StreamableHttpServerConfig. However, these items are missing in current rustdocs. This is because they are marked with #[cfg(not(feature = "local"))], while you pass all-features = true to docs.rs when building docs. This leads the rustdoc to ignore these items.

To Reproduce
Steps to reproduce the behavior:

1. Open the latest doc in docs.rs and search for such items

Expected behavior
Such items are present in rustdoc

Additional context
I think a proper workaround is to let docs.rs build rustdoc without local feature.

Hi, I've been looking into this and traced the root cause.

Proposed approach: In crates/rmcp/Cargo.toml, replace the docs.rs metadata all-features = true with an explicit feature list that excludes local. For example: features = ["client", "server", "transport-sse-server", "transport-streamable-http-server", ...] listing all features except local. This ensures docs.rs builds include items gated behind cfg(not(feature="local")).

I'll open a draft PR shortly. Happy to adjust based on your preference.
