Preliminary support for MCP

[djperrefort]

Adds preliminary support for the Model Context Protocol (MCP). Uses FastMCP and its from_fastapi functionality to optionally generate an MCP app from the dynamically built FastAPI application.

Future work:

from_fastapi() generates tool names from operation_ids, which FastAPI
auto-generates as things like fetch_multiple_records_from_the_table__db__users__get. Those
are functional but not great for LLM reasoning. Adding explicit operation_id values to each
route in create_table_router would directly improve how well an LLM understands what each
tool does.

FastAPI uses the handler's docstring as the tool description.
The current handlers have docstrings but they're generic: "Fetch a list of records from the
database". This doesn't tell the LLM anything about which table or what the data represents. Passing
table-aware descriptions into the handlers would help significantly.
