feat(cmdb-assistant): add data quality validation v1.1.0

Add validation hooks, best practices skill, and new commands to enforce
NetBox data quality standards:

Hooks:
- SessionStart: Test NetBox connectivity, report data quality issues
- PreToolUse: Validate VM/device parameters before create/update

New Commands:
- /cmdb-audit: Data quality analysis (vms, devices, naming, roles)
- /cmdb-register: Register current machine with running applications
- /cmdb-sync: Sync machine state with NetBox, detect drift

Best Practices Skill:
- Dependency order (regions -> sites -> devices -> VMs)
- Site/tenant/platform assignment requirements
- Naming conventions enforcement
- Role consolidation guidance

Updated agent with validation requirements, dependency order checks,
naming convention warnings, and duplicate prevention.
