[Feature] Resiliency & Reliability Review

[djm81]

Summary

• Track the resiliency review pillar for runtime robustness and operational scalability checks.
• Define the shared CLI and report contracts in specfact-cli while paired runner/bundle work lands later in specfact-cli-modules.
• Keep sequencing aligned with openspec/CHANGE_ORDER.md and the five-pillar governance epic.

Scope

• resiliency finding model and severity contract
• review report envelope integration
• CLI surface for resiliency review evidence
• downstream evidence handoff into distillation

Child changes

• review-resiliency-01-contracts (nold-ai/specfact-cli)
