fix: address second round of code review feedback

- Move VERSION guard into recipe to avoid global parse-time error
- Centralize owner/repo via GoReleaser template variables
  (.Env.GITHUB_REPOSITORY_OWNER, .ProjectName) to avoid hardcoding
- Remove hardcoded release.github.owner (GoReleaser auto-detects)
