feat: bruin mcp poc

[terzioglub]

Wanted to kick off the initial MCP server implementation. You can think of this PR as a very basic proof of concept or kind of a "hello world" for MCP in Bruin.
What this pr adds:

1. New bruin mcp command: Starts a JSON-RPC server that communicates via stdin/stdout
2. MCP Protocol Support: Implements the MCP handshake (initialize/initialized) and core methods
3. Basic Tool Framework: Provides a single get_bruin_info tool that returns information about Bruin's features and capabilities

How to configure

1. go to cursor (top left) -> settings -> cursor settings -> MCP -> add new global mcp server and add the following

{
    "mcpServers": {
      "bruin": {
        "command": "path/to/your//bin/bruin",
        "args": ["mcp", "--debug"],
        "env": {}
      }
    }
  }

that's it dont forget to build your project after merging or getting this branch to your local
