Jon Chery 2c26a6d54f docs(P03): full-stack examples — 5 jobspecs + rendered artifacts + walkthrough

P03 — full-stack example with ingress configured (REQ-094; gate C-20).

examples/full-stack/:
- web-app.md: kind Service, process runtime, 3 replicas, Unix socket
  (default R-007), rolling update, constraints (node.role==web),
  affinity (zone==a weight 80), lifecycle hooks (post_start/pre_stop).
- api.md: kind Service, process runtime, 2 replicas, TCP opt-in
  (service.bind: 127.0.0.1, R-007), canary update with manual promote,
  constraints (node.role==api, node.cpus>=2), env vars.
- worker.md: kind Job, process runtime, one-shot, timeout 300s, env
  vars, lifecycle hooks (register/drain).
- log-shipper.md: kind Service (DaemonSet workaround — parser gap),
  process runtime, constraints (node.role==logs), env vars. Notes the
  v0.9 parser gap (schedule: block not wired) in a callout.
- postgres.md: kind Service, process runtime, 1 replica, blue-green
  update, volumes with replication (replicate:peer-b,peer-c via
  Syncthing), constraints (node.role==db, node.cpus>=4, node.memory>=8192).
- rendered/: Traefik dynamic YAML (web-app, api) + systemd units
  (web-app, api, log-shipper) showing what Orca generates on target nodes.
- README.md: end-to-end walkthrough (init -> node join -> capacity set
  -> ns create -> job run -> list --watch -> inspect rendered -> verify
  ingress -> drain/rollback). Cross-links to docs/ingress.md.
- examples_test.go: Go test that parses + validates all 5 jobspecs
  against the current parser and schema validators (gate C-20).

All 5 jobspecs pass jobspec.ParseFile + schema.ValidatorFor(kind).

API Server

Backend API service binding to 127.0.0.1:9090 (TCP opt-in, R-007). Canary update strategy with manual promote. Two replicas with CPU constraint (>= 2 vCPUs) and API-role node selection.
