fix(ci): drop [tool.uv.sources] override pointing at sibling python-sdk

CI workspace doesn't have ../python-sdk on the runner, so
`uv sync --frozen --all-extras` fails with "Distribution not found".
The local-dev convenience overlay belongs in a non-committed
configuration; with this removed, both local and CI resolve agentscore-py
from PyPI as a normal dep.

Re-resolved uv.lock against the simplified source set + upgraded all
extras (uv sync --upgrade --all-extras) — no changes to extras since
they were already at latest after the prior commit.
