[Bug] skillOverrides not applied to plugin-provided skills

Bug Description
▎ skillOverrides has no effect on plugin-provided skills.
▎
▎ ~/.claude/settings.json sets "off" for six figma skills:
▎ "skillOverrides": {
▎ "figma:figma-code-connect": "off",
▎ "figma:figma-create-design-system-rules": "off",
▎ "figma:figma-generate-diagram": "off",
▎ "figma:figma-generate-library": "off",
▎ "figma:figma-use": "off",
▎ "figma:figma-use-figjam": "off"
▎ }
▎ All six still appear in the session's skill listing. Non-plugin skills respond correctly to disable-model-invocation in frontmatter, so this looks specific to plugin-sourced skills — possibly a key-namespacing mismatch (plugin:skill vs the internal id). Cost is ~1.5k chars of listing per session, which /doctor Check 6 identifies as the single largest resident context item. figma@claude-plugins-official, CC 2.1.219 native, macOS.
