This change makes the `tool` macro's output safe for the `missing_docs` lint, by emitting a doc comment for the generated `[tool]_tool_attr` function. This doc comment is emitted regardless of whether the tool function is public, for simplicity. We are building an MCP server using `rmcp` and discovered that the current crate was not compatible with the `#![deny(missing_docs)]` lint which we use everywhere. Tested by modifying the `test_tool_macros.rs` test to use `#![deny(missing_docs)]` and adding doc comments to all pub fns and structs in that file. None. Fixes modelcontextprotocol#438.
