annguyenNous 83a7d0b601 fix(skills): fix transaction ordering in reset_bundled_skill and handle read-only files in rmtree
Two related bugs in tools/skills_sync.py affecting Nix-store and
immutable-package installs:

**#34972 — reset_bundled_skill corrupts manifest on rmtree failure:**
The function deleted the manifest entry BEFORE attempting rmtree. If
rmtree failed (read-only files from Nix store), the function returned
early — leaving the skill in a manifest-less limbo state where future
syncs silently skip it forever.

Fix: reorder steps — attempt rmtree FIRST, only delete manifest entry
after rmtree succeeds. If rmtree fails, nothing is changed.

**#34860 — stale .bak directories after sync:**
sync_skills() called shutil.rmtree(backup, ignore_errors=True) which
silently failed on read-only files, leaving persistent .bak dirs.

Fix: add _rmtree_writable() helper that makes files writable via an
onerror callback before retrying removal. Used in both sync_skills()
backup cleanup and reset_bundled_skill().
