security: add skill/plugin code safety scanner (#9806)

* security: add skill/plugin code safety scanner module

* security: integrate skill scanner into security audit

* security: add pre-install code safety scan for plugins

* style: fix curly brace lint errors in skill-scanner.ts

* docs: add changelog entry for skill code safety scanner

* style: append ellipsis to truncated evidence strings

* fix(security): harden plugin code safety scanning

* fix: scan skills on install and report code-safety details

* fix: dedupe audit-extra import

* fix(security): make code safety scan failures observable

* fix(test): stabilize smoke + gateway timeouts (#9806) (thanks @abdelsfane)
