fix(plugins): log silently ignored execAsRoot errors during uninstall

Plugin uninstall had two sites where execAsRoot errors were discarded:
- Skill directory removal (plugins_install.go:125) — orphaned skill dirs
  if rm -rf failed silently
- CLAUDE.md marker stripping (plugins_install_pipeline.go:326) — stale
  plugin content left in CLAUDE.md if awk script failed

Both now log the error without failing the overall uninstall (best-effort
 cleanup), giving operators visibility into incomplete uninstalls.
