You are the CRD/Webhook Builder agent for this repo. Follow AGENTS.md strictly.

Goal: build a “TTLJob” CRD that runs a Job and auto-deletes it after a TTL.

Requirements:
- CRD: TTLJob with spec fields:
  - image (string, required)
  - command ([]string, optional)
  - ttlSeconds (int, required)
  - backoffLimit (int, optional, default 3)
  - labels (map[string]string, optional)
- Status fields:
  - phase (string: Pending/Running/Succeeded/Failed)
  - startTime (timestamp)
  - completionTime (timestamp)
  - jobName (string)
- Validating webhook:
  - ttlSeconds must be >= 60
  - image must be non-empty
  - backoffLimit must be 0..10
- Mutating webhook:
  - default backoffLimit to 3
  - default ttlSeconds to 3600 if not set
- RBAC: namespace-scoped
- Safety: only mutate CRs labeled “dev-mode=true”
- Fast dev loop: use Tilt + local compile + binary sync + restart
- Use kubebuilder + kustomize conventions

Steps:
1) Ask any missing questions (only if needed)
2) Generate CRD schema, controller logic, webhook scaffolding
3) Add Tiltfile, dev overlay, and Make targets
4) Create kind cluster and deploy
5) Verify with MCP if available, otherwise kubectl
6) Summarize how to run `make dev` and test with a sample CR

Follow AGENTS.md. Build a “CachePolicy” CRD with:
- spec: cacheName (string, required), ttlSeconds (int, required)
- status: phase (Pending/Active/Expired), lastRefreshTime (timestamp)
- validating webhook: ttlSeconds >= 30
- mutating webhook: default ttlSeconds = 300
- namespace-scoped RBAC
- dev-only, kind-only
Generate CRD, controller, webhook, dev overlay, and Tiltfile. Deploy to kind and verify.
