Squashes all pre-rewrite history into a single root commit. Previous tree: - 14506 commits including upstream Infisical fork history - Multiple merge chains carrying pre-purge content Force-rewrite per disk-space reclamation discipline. GHCR images (1.9.9, 1.9.11) remain immutable; their git lineage is no longer materialized.
