fix(skills): add sibling XML auto-resolve for directory paths

When a directory is passed (e.g. src/Name or Catalogs/Name), the
auto-resolve now also checks for a sibling file ../Name.xml, which
is the standard layout for both 1C config dumps and EPF/ERF sources.

Affected: meta-info, meta-edit, meta-validate, epf-validate,
subsystem-edit, subsystem-info, subsystem-validate (7 scripts).
