claude_uninstall only stripped the CLAUDE.md section, so `graphify uninstall`
and `graphify claude uninstall` orphaned the whole installed skill tree
(SKILL.md + references/ + version stamp) - gemini_uninstall already removes its
skill, this makes claude consistent. The #1121 split made the orphan a 10-file
directory; this restores the removal that the alternative PR #1119 had. Scoped
name removal preserves sibling user files; project-scope uninstall passes
project=True so it never touches the user-scope skill.
Verified: claude/bare uninstall now remove the tree and keep a sibling
user_notes.md; full suite 1755 passed; real extract still builds a clean graph.
