feat: Tools as MCP

[monoxgas]

Notes

• Add as_mcp helper to turn rigging tools into a FastMCP server
• Updated docs around MCP integrations

---

Generated Summary

• Added the new as_mcp function, which creates a FastMCP server instance from Rigging tools or raw Python functions and handles conversion to MCP-compatible types.
• Updated documentation in docs/api/tools.mdx and docs/topics/tools.mdx to include usage details, examples, and source code for as_mcp.
• Modified migration documentation to change references from rigging.integrations to rigging.tools for both MCP and Robopages integrations.
• Updated export lists in rigging/init.py and rigging/tools/init.py to expose the new as_mcp function.
• Extended the MCP communication logic in rigging/tools/mcp.py with helper methods (_convert_rigging_return_to_mcp and _create_mcp_handler) to support proper serialization of tool responses.

Generated Summary

• Introduced the new as_mcp function to create a FastMCP server from a collection of Rigging tools or raw Python functions.
• Updated documentation in both the API and topics pages to explain as_mcp usage with clear examples for exposing and consuming MCP tools.
• Modified the rigging/init.py and rigging/tools/init.py files to export the new as_mcp function.
• Enhanced the MCP module by adding helper functions (_convert_rigging_return_to_mcp and _create_mcp_handler) to properly bridge Rigging tool returns to the MCP format.
• Added detailed examples showing how to run an MCP server using as_mcp and how to connect to MCP servers using both stdio and sse transports.
