fix(ci): prevent version-manifest job from being skipped on tag push (#10)

The version-manifest job was silently skipped on v1.6.0 due to GitHub
Actions transitive needs-chain behavior: when auto-version is skipped
(tag push), build-and-push uses always() to run anyway, but
version-manifest inherited the skip from the ancestor chain. Adding
always() with an explicit success check ensures the job runs whenever
build-and-push succeeds on a tag push.
