- Materializer derives the manifest GitContext from RunTarget::validate()
instead of hand-building it and re-parsing the repository slug
- Drop parse_github_repository_slug and InvalidRepositorySlug, now unused
- Store reuses Automation::git_target() instead of a private duplicate
- Legacy TOML import returns the target directly rather than a tuple
- Automation target migration updates columns with a single UPDATE ... FROM
- Web: share gitTarget(), targetFromFormValues(), and one SHA validator
across the automation form, list, detail, new, and edit views
