Add /opsx:porting-guide skill that generates detailed human-readable
implementation guides as a companion to /opsx:export-spec. The AI spec
targets the agent; the porting guide targets the human developer with
design rationale, task-by-task notes, troubleshooting tables, and
rollback plans.
Generate the full NL XVA Pricer export bundle for CRC:
- nlxva-pricer-spec.md (AI-targeted portable spec)
- nlxva-pricer-openspec.md (OpenSpec proposal/design/tasks)
- nlxva-pricer-porting-guide.md (human implementation guide)
