# audit-missing-git.sh - Audit @ts packages for git and workflow configuration
#
# Scans all @ts/* directories and categorizes packages by their publishing
# configuration and git/workflow setup status.
#
# Usage:
#   ./scripts/analysis/audit-missing-git.sh           # Run audit
#   ./scripts/analysis/audit-missing-git.sh --quiet   # Only show problems
#
# Categories:
#   PUBLISHABLE_NO_GIT      - _.publish=true but missing .git directory
#   PUBLISHABLE_NO_WORKFLOW - _.publish=true but missing .forgejo/workflows/
#   INTERNAL                - No _.publish=true (internal/tooling packages)
#   PROPERLY_CONFIGURED     - Has both .git and workflows
