SSE transport has been removed from the MCP specification in favor of
streamable HTTP. This removes all SSE-specific transport code:
- Remove `transport-sse-client` and `transport-sse-server` features
- Remove `SseClientTransport` and `SseServer` types
- Remove SSE-specific examples (`counter_sse`, `counter_sse_directly`)
- Migrate auth examples from SSE to streamable HTTP
- Update tests to remove SSE transport usage
- Update documentation
BREAKING CHANGE: The following have been removed:
- `transport-sse-client` feature
- `transport-sse-client-reqwest` feature
- `transport-sse-server` feature
- `SseClientTransport` type
- `SseServer` type
- `sse_client` and `sse_server` modules
Users should migrate to streamable HTTP transport which provides
equivalent functionality. See `StreamableHttpClientTransport` and
`StreamableHttpService` for the replacement APIs.

* feat(rmcp): enhance transport features by decoupling reqwest
- Added reqwest features for reqwest-based implementations.
- Updated documentation

* refactor: refactor tool macros and router implementation
- Updated the `#[tool(tool_box)]` macro to `#[tool_router]` across various modules for consistency.
- Enhanced the `Calculator`, `Counter`, and `GenericService` structs to utilize `ToolRouter` for handling tool calls.
- Introduced `Parameters` struct for better parameter handling in tool functions.
- Added new methods for listing tools and calling tools in server handlers.
- Improved test cases to reflect changes in tool routing and parameter handling.
- Updated documentation and examples to align with the new router structure.
