[Integration DoD][MW-11] Close docs/runbook gaps for high-risk integrations

[github-actions]

This issue is auto-generated from INTEGRATION_DOD_MAP.md by the nightly DoD gap sync workflow.

Gap

• ID: MW-11
• Owner (area-owner): Docs

Acceptance Criteria

• Registry/drop, skill catalog, media provider, connector specifics, and CUA operations have setup, failure, and verify guidance.

Verification Commands

bun run docs:build

Risk

• Slower onboarding and repeated configuration mistakes.

Addressed in PR #773.

Gap found: docs/guides/registry.md has the full operational runbook for registry/drop operations (setup checklist, failure modes, recovery procedures, verification commands) but was completely orphaned from the Mintlify navigation — unreachable by users. docs/plugins/registry.md (which IS in the nav) only covers technical architecture with no operational guidance.

Fix: Added "guides/registry" to the Advanced > Plugins nav group in docs.json.

All 5 acceptance criteria topics now have their runbook guides wired into the nav:

• Registry/drop: guides/registry (was orphaned, now fixed) + rest/drop
• Skill catalog: plugins/skills
• Media providers: guides/media-generation
• Connector specifics: guides/connectors
• CUA operations: plugin-registry/computeruse
