Validate final selected skill roots and references before preview, approval,
and client/Hopper changes, with a repeated installation-boundary check.
Preserve interactive unselected-client choices and registration-only setup.
Share typed directory/read observations across setup, doctor, and update;
report unmanaged paths and unknown reads with actionable paths/reasons.
Retain uninstall child outcomes and ownership manifests when cleanup remains.
Shared single-pass inspection retains all unreadable paths after stale or
missing files and keeps observed metadata, without duplicate manifest reads.
Absent installed files do not depend on generated bundled bytes.
Validation: 217 related tests, 41 final CLI/MCP and filesystem checks, and all
7,446 source tests in 508 files pass (eight platform/condition skips).
Static/docs checks pass. Normal four-call
install/rerun/repair/uninstall tasks preserve results and output token counts.
No native Windows follow-up or arbitrary concurrent swap containment claim.
Fixes#3057.
