actions/checkout treats short SHAs as branch name patterns, causing
fetch failures. Always resolve --ref to a full 40-char SHA before
dispatching the workflow.

When manually dispatching a container build with --ref, the build job
now checks out the specified commit instead of the branch HEAD. This
allows building containers from feature branches before merging.

## Summary
- Replace git-tag-triggered container builds with path-based triggers on main and workflow_dispatch
- Image tags now encode upstream app version + commit SHA (`vX.Y.Z-<sha>`) for full traceability
- Replace `container-tag-and-release` task with `container-build-and-release` (dispatches workflows via Forgejo API)
- Update dagger `publish()` to accept `commit_sha` parameter
- Update all docs and references to the new workflow
## Deployment and Testing
- [ ] Merge to main
- [ ] `mise run container-build-and-release <name>` for each container to populate new-format tags
- [ ] Verify tags in registry via `mise run container-list`
- [ ] Existing images untouched — old tags remain available
