fix: bug: supervisor hardcodes ops repo expectation — fails silently on deployments without one (#544)

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.

+# Git State Recovery — Best Practices
+
+## Git State Issues (P2)
+
+When git repo is on wrong branch or in broken rebase state:
+
+### Wrong Branch Recovery
+```bash
+cd "$PROJECT_REPO_ROOT"
+git checkout "$PRIMARY_BRANCH" 2>/dev/null || git checkout master 2>/dev/null
+```
+
+### Broken Rebase Recovery
+```bash
+cd "$PROJECT_REPO_ROOT"
+git rebase --abort 2>/dev/null || true
+git checkout "$PRIMARY_BRANCH" 2>/dev/null || git checkout master 2>/dev/null
+```
+
+### Stale Lock File Cleanup
+```bash
+rm -f /path/to/stale.lock
+```
+
+### Prevention
+- Always checkout primary branch after rebase conflicts
+- Remove lock files after agent sessions complete
+- Use `git status` to verify repo state before operations
