Forgejo Actions doesn't consistently honor `on.push.branches` as a
filter — the merge commit landing on main after a release PR was still
triggering the full CI workflow on a SHA that had already passed on
dev, burning ~1 minute of runner time for no reason.
The `build` job already had a ref guard, so no duplicate images were
being pushed, but typecheck/lint/test ran unconditionally. Add the
same guard (`refs/heads/dev` or `refs/tags/v*`) to those three so main
pushes trigger the workflow but every job skips immediately with zero
runner time.
Also tightened the build job's tag filter from `refs/tags/` to
`refs/tags/v` for consistency with the new guards and to avoid ever
building from a non-version tag.
