docs(rules): deployment strategies + generation suffix

Refresh the three rules files to match the new executor behavior:

- docker-orchestration.md: rewrite DeploymentExecutor Details with
  container naming scheme ({...}-{replica}-{generation}), strategy
  dispatch (blue-green vs rolling), and the new DEGRADED semantics
  (post-deploy only). Update TraefikLabelBuilder + ContainerLogForwarder
  bullets for the generation suffix + new cameleer.generation label.
- app-classes.md: DeploymentExecutor + TraefikLabelBuilder bullets
  mirror the same.
- core-classes.md: add DeploymentStrategy enum; note DEGRADED is now
  post-deploy-only.

 ## runtime/ — Docker orchestration
 
 - `DockerRuntimeOrchestrator` — implements RuntimeOrchestrator; Docker Java client (zerodep transport), container lifecycle
-- `DeploymentExecutor` — @Async staged deploy: PRE_FLIGHT -> PULL_IMAGE -> CREATE_NETWORK -> START_REPLICAS -> HEALTH_CHECK -> SWAP_TRAFFIC -> COMPLETE. Container names are `{tenantId}-{envSlug}-{appSlug}-{replicaIndex}` (globally unique on Docker daemon). Sets per-replica `CAMELEER_AGENT_INSTANCEID` env var to `{envSlug}-{appSlug}-{replicaIndex}`.
+- `DeploymentExecutor` — @Async staged deploy: PRE_FLIGHT -> PULL_IMAGE -> CREATE_NETWORK -> START_REPLICAS -> HEALTH_CHECK -> SWAP_TRAFFIC -> COMPLETE. Container names are `{tenantId}-{envSlug}-{appSlug}-{replicaIndex}-{generation}`, where `generation` is the first 8 chars of the deployment UUID — old and new replicas coexist during a blue/green swap. Per-replica `CAMELEER_AGENT_INSTANCEID` env var is `{envSlug}-{appSlug}-{replicaIndex}-{generation}`. Branches on `DeploymentStrategy.fromWire(config.deploymentStrategy())`: **blue-green** (default) starts all N → waits for all healthy → stops old (partial health = FAILED, preserves old untouched); **rolling** replaces replicas one at a time with rollback only for in-flight new containers (already-replaced old stay stopped; un-replaced old keep serving). DEGRADED is now only set by `DockerEventMonitor` post-deploy, never by the executor.
 - `DockerNetworkManager` — ensures bridge networks (cameleer-traefik, cameleer-env-{slug}), connects containers
 - `DockerEventMonitor` — persistent Docker event stream listener (die, oom, start, stop), updates deployment status
-- `TraefikLabelBuilder` — generates Traefik Docker labels for path-based or subdomain routing. Also emits `cameleer.replica` and `cameleer.instance-id` labels per container for labels-first identity.
+- `TraefikLabelBuilder` — generates Traefik Docker labels for path-based or subdomain routing. Per-container identity labels: `cameleer.replica` (index), `cameleer.generation` (deployment-scoped 8-char id — for Prometheus/Grafana deploy-boundary annotations), `cameleer.instance-id` (`{envSlug}-{appSlug}-{replicaIndex}-{generation}`). Router/service label keys are generation-agnostic so load balancing spans old + new replicas during a blue/green overlap.
 - `PrometheusLabelBuilder` — generates Prometheus Docker labels (`prometheus.scrape/path/port`) per runtime type for `docker_sd_configs` auto-discovery
 - `ContainerLogForwarder` — streams Docker container stdout/stderr to ClickHouse with `source='container'`. One follow-stream thread per container, batches lines every 2s/50 lines via `ClickHouseLogStore.insertBufferedBatch()`. 60-second max capture timeout.
 - `DisabledRuntimeOrchestrator` — no-op when runtime not enabled
