feat: role-compile OutputDir accepts config root (like meta-compile)

- OutputDir now accepts config root dir — creates Roles/ subdirectory
- Back-compat: if OutputDir ends with "Roles", uses it as-is
- Configuration.xml lookup adjusted accordingly
- Updated SKILL.md, PS1, PY scripts (v1.3)
- Updated test cases and snapshots for new Roles/ path
