Switch mcp-run-python server to use deno

[samuelcolvin]

Switch from node/npm/npx to deno so we can ensure isolation using deno's sandboxing.

Usage of the new JSR package:

deno run \
  -N -R=node_modules -W=node_modules \
  --node-modules-dir=auto \
  jsr:@pydantic/mcp-run-python \
  [stdio|sse|warmup]
