Change Description

ext-fprime-cfs-reference.yml launched fprime-gds --ip-client --ip-port 15010, the TCP port of the fprime_gds bridge app that fprime-community/fprime_cfs_reference#44 removed on 2026-11-05. The reference FSW now talks to the ground only through CI_LAB/TO_LAB, reached with the cfs-lab communication plugin and cfs framing plugin from the fprime_cfs Python package. This PR switches gds-args to --communication-selection cfs-lab --framing-selection cfs, matching the reference repository's own build-and-test.yml.

Rationale

Every External Repo: cFS Reference run since the #44 merge fails: the comm.py.log artifact shows the GDS retrying Connection refused on 0.0.0.0:15010 for the whole run while FSW starts normally (CI_LAB listening on UDP port: 1234), so all 9 integration tests time out with no events or telemetry. The failure shows up as a red check on every open PR (e.g. #6336) and on the nightly schedule.

Testing/Review Recommendations

• The External Repo: cFS Reference job on this PR is the test. The fprime-cfs plugin package is already installed by external-repository-setup from the target's requirements.txt (./libs/fprime_cfs/python), so no further workflow change is needed.
• Compare with fprime-community/fprime_cfs_reference .github/workflows/build-and-test.yml (green on devel).

Future Work

None.
