feat(render-svc+node-agent): add job-claim endpoint and build node-agent skeleton
render-svc:
- db: ClaimJob() — atomic SELECT FOR UPDATE SKIP LOCKED; transitions job to
Preparing, marks node Busy in a single transaction
- models: ClaimJobRequest + ClaimedJob types
- handlers/internal: POST /v1/internal/render/jobs/claim — 200 with job or 204 when queue empty
- main: register the claim route under /v1/internal (nodeAuth)
services/node-agent/ (new Go module github.com/flatrender/node-agent):
- internal/config: env-var based config (NODE_ID required, sensible defaults)
- internal/client: typed orchestrator HTTP client (Online, Heartbeat, ClaimJob,
Complete, Fail, ReportCrash) — X-Node-Signature auth
- internal/runner: AE render via aerender.exe or mock (for dev without AE)
- cmd/agent/main: register online → heartbeat loop (5s) + poll loop (3s) →
claim job → run render → report complete/fail; health endpoint on :7777
- Dockerfile: cross-compiles to Windows amd64 static binary
