### Feature Request ✨️ Safety-Critical Robotics: Why ROS2 Needs Deterministic Tool Routing

Hi ROS2 Team,

Bringing ROS 2 to the MCP standard is a huge step for AI-driven robotics. However, in robotics, non-deterministic behavior can be dangerous. Relying on an LLM to decide when to call a /cmd_vel or a /stop service introduces unacceptable latency and unpredictability.

I’m building WisePick, a 0.0s latency deterministic routing layer. I propose we integrate WisePick as a "Hard-Wired Controller" for ROS 2 MCP.

When a specific "Safety Condition" or "Standard Operation" is detected, Wi

### Update base image to prevent symbol lookup error

It appears that new jazzy built-in interfaces were recently released, which are now causing this error in newly built ros2_mcp servers:
`/app/.venv/bin/python3: symbol lookup error: /opt/ros/jazzy/lib/libbuiltin_interfaces__rosidl_typesupport_fastrtps_c.so: undefined symbol: _ZN8eprosima7fastcdr3Cdr9serializeEj`

We were able to resolve that error, adding `RUN apt-get update && apt-get upgrade ros-jazzy-rosidl-typesupport-fastrtps-cpp -y` in the Dockerfile (line 11) before installing the other p

### Add support for Streamable HTTP

SSE transport is being deprecated (https://modelcontextprotocol.io/docs/concepts/transports#server-sent-events-sse-deprecated). In its place Streamable HTTP is being used (https://modelcontextprotocol.io/docs/concepts/transports#streamable-http)

### Add `pre-commit`

Add `pre-commit` configuration to format, link and type check the code before commit.
Proposal:
- formatting: ruff (with black formatter configuration),
- linting: ruff,
- type check: mypy
