Add Python bindings crate, FFI, workflow, and examples for RMCP Rust SDK

[tarunanand-dev]

Overview

This PR introduces Python bindings for the RMCP Rust SDK using PyO3, along with a GitHub Actions workflow, tests, and example usage. The bindings enable Python applications to interact with the Rust SDK via FFI, including an example SSE client.

What’s Included
New Rust crate for Python bindings under bindings/python
PyO3-based FFI for seamless Rust ↔ Python integration
Example Python SSE client (bindings/python/examples/clients/src/sse.py)
GitHub Actions workflow for building and testing Python bindings
Tests for Python bindings (bindings/python/tests/)
.gitignore files for Rust and Python artifacts

How Has This Been Tested?

An example working Python client and a few test cases have been added.

Additional context

README: Python Bindings Setup & Example Usage

1. Prerequisites
   Rust (latest stable, with cargo)
   Python 3.8+ (with pip)
   maturin for building the Python extension (install via pip install maturin)
2. Build the Python FFI Extension

cd bindings/python
maturin develop # or: maturin build && pip install target/wheels/*.whl

This will compile the Rust FFI library and install the Python package in your environment.

3. Run the Rust Server
   In a separate terminal, start the Rust SDK server (example using the rmcp crate):

cd examples
cargo run --example servers_axum

4. Run the Python SSE Client Example
   With the server running, in another terminal:

cd bindings/python/examples/clients/src
python sse.py
