chore(deps): consume released pararamio-aio 3.0.31 (#3)

Drop the dev-only [tool.uv.sources] override that pointed pararamio-aio
at ../py-pararamio/packages/pararamio_aio for local development of the
X-UserToken work. pararamio-aio 3.0.31 is now on PyPI and contains the
user_token=AsyncPararamio kwarg, so the override is no longer needed.

- pyproject.toml: remove [tool.uv.sources] block and its TODO preamble
- packages/pararam-nexus-mcp/pyproject.toml: bump pararamio-aio>=3.0.13
  to pararamio-aio>=3.0.31
- uv.lock: regenerated against PyPI; pararamio-core removed from the
  resolved set (aio 3.0.31 is self-contained)

Verified end-to-end against api.pararam.io with a real X-UserToken
after the upgrade: limited mode still boots cleanly, 11 tools register,
get_chat returns chat metadata over the published aio.
