fix: resolve FINDINGS — synonyms, path resolution, exit codes

Skill fixes (all ps1+py, version bumped to v1.1):
- role-compile: accept "rights" as synonym for "objects"
- subsystem-compile: accept "objects" as synonym for "content"
- form-add: resolve directory path to .xml (like meta-validate)
- form-info: resolve directory path to Ext/Form.xml (like form-validate)
- mxl-compile: support absolute OutputPath (IsPathRooted check)
- meta-remove: exit 1 when object not found; v1.1
- cfe-patch-method: accept plural type names (Catalogs → Catalog)

Test fixes:
- basic-role.json: use canonical "objects" key
- basic.json (subsystem): use canonical "content" key
- catalog-form.json: fix outdated DSL format
- New synonym test cases for role-compile and subsystem-compile
- error-not-found.json: expect error (exit 1)
