B-M3: ClawHub package downloads are not enforced with integrity verification.

ClawHub downloads could install plugin archives without enforcing archive or per-file integrity metadata.

OpenClaw is a user-controlled local assistant. This advisory is scoped to the OpenClaw trust model and does not assume a multi-tenant service boundary.

The issue was fixed on main and is available in the patched npm version listed above. The verified fixed tree is commit d7c3210cd6f5fdfdc1beff4c9541673e814354d5.

The fix was re-checked against main before publication, including targeted regression tests for the affected security boundary.
