Add OPS repo presence detection in supervisor-run.sh with degraded mode support:
- Detect if OPS_REPO_ROOT is missing and log WARNING message
- Set OPS_REPO_DEGRADED=1 flag and configure fallback paths
- Bundle minimal knowledge files as fallback for degraded mode
- Update formula to use OPS_KNOWLEDGE_ROOT, OPS_JOURNAL_ROOT, OPS_VAULT_ROOT
- Support local vault destination and journal fallback when ops repo absent
Knowledge files bundled: disk.md, memory.md, ci.md, git.md, dev-agent.md,
review-agent.md, forge.md
The supervisor now runs with full functionality when ops repo is available,
or gracefully degrades to local paths when absent, making the failure mode
explicit rather than silent.
