marcus 7de4b56962 v0.2.2: BUILD_FAILED pull failure aborts redeploy with clear message
Remove contextlib.suppress from the image pull step in the BUILD_FAILED
redeploy path. A failed pull (e.g. non-existent tag) now immediately
returns an actionable error pointing to update_image_tag instead of
silently continuing and starting the project with stale/missing image.

Also bumps version 0.2.1 → 0.2.2 and adds CHANGELOG entry.
