fix(release): release_workspaces no-cascade + drop euclid_pipeline (#78)

Two fixes to the release_workspaces matrix:

1. Add `fail-fast: false`. Default fail-fast was cancelling all sibling
   matrix jobs when any one failed — in run 25211061207 (release of
   2026.5.1.1), the euclid_pipeline auth failure cancelled
   autogalaxy_workspace, autolens_workspace, HowToFit, HowToGalaxy, and
   HowToLens, leaving 5 of 7 workspaces un-tagged for that release.

2. Remove the Jammy2211/euclid_strong_lens_modeling_pipeline matrix
   entry. The repo lives in the Jammy2211/ user namespace, but the job's
   PAT (PAT_PYAUTOLABS) is scoped to the PyAutoLabs/ org only, so every
   release_workspaces run for euclid_pipeline failed with
   "Permission to Jammy2211/euclid_strong_lens_modeling_pipeline.git
   denied to Jammy2211" → exit 128.

To re-enable euclid auto-tagging in future:
- Create a fine-grained PAT scoped to the Jammy2211 user account with
  contents:write on the euclid repo.
- Add it as a PAT_JAMMY repo secret on PyAutoLabs/PyAutoBuild.
- Re-add the matrix entry with a `pat: PAT_JAMMY` field, following the
  per-matrix pat pattern already used in the `release` job (lines
  575-597 of this file).

Until then, euclid_pipeline gets tagged manually whenever its workspace
should pin to a new lib version.
