Package detect inspects a directory tree for project signals (go.mod, package.json, …) and reports the stack so @init can pre-tick the right modules.

Package meta dispatches `@`-sigil meta-commands — handled by justx, never passed to `just`.

Package modules holds the built-in, data-driven justfile modules.

Package router translates expressive recipe names (`:`, `!`, `?`) into the mappings real `just` understands, then execs `just`.

Package scaffold composes selected modules into a justfile, wrapping each module's recipes in `# >>> justx:<id>` / `# <<< justx:<id>` provenance fences so v2's @upgrade can re-sync managed regions without clobbering user edits.
