fix(uninstall): provenance-gate the shape-2 and cursor sweeps; document the alias-name coupling
Three ways gstack-uninstall could touch a user's own skills: - Shape 2 (real dir + symlinked SKILL.md) matched the link target against a bare *gstack* substring, so a skill symlinked from ~/tools/gstack-fork/ was wiped on uninstall. The gate now requires "gstack" as an anchored path segment (gstack/*|*/gstack/*, same pattern as shape 1) AND the dir name in gstack's skill inventory (parity with shape 3); anything else is listed to stderr, never deleted. - The new Cursor removals (~/.cursor/skills/gstack* and repo-local .cursor/skills/gstack*) rm -rf'd any glob match with no provenance check, so a hand-written ~/.cursor/skills/gstack-fork-notes was swept. Real dirs now require the AUTO-GENERATED banner in SKILL.md; non-matching dirs are kept and listed. Legacy codex/factory/kiro globs are untouched (tracked in TODOS as a follow-up). - The _INVENTORY seed list hardcodes alias names created by setup's _install_alias_skill_md; both sites now carry mirrored keep-in-sync comments so a renamed alias can't silently strand its dir. The skipped-entry report moves to the end of the run so cursor skips are listed alongside the Claude ones. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
