## Summary - Extract PHP/Laravel commands to `core/php` repo (42 files, standalone module) - Extract CI/release + SDK commands to `core/ci` repo (10 files) - Remove `internal/variants/` build tag system entirely - Move all 30 remaining command packages from `internal/cmd/` to top-level `cmd/` - Rewrite `main.go` with direct imports — no more variant selection - PHP and CI are now optional via commented import lines in main.go Co-authored-by: Claude <developers@lethean.io> Reviewed-on: #2 Co-authored-by: Charon <charon@lthn.ai> Co-committed-by: Charon <charon@lthn.ai>
