Andrew Stoltz 2f796a2ebd selenium: migrate hub + 3 nodes + service + ingressroute into ArgoCD 
Previously orphan kubectl-applied since the Selenium Grid was first set
up. The `infra-selenium` ArgoCD app existed but only managed
`network-policy.yaml` — the deployments themselves drifted whenever
anyone `kubectl set env`'d or `kubectl scale`'d.

This commit captures the live state (with the 2026-05-25 maxSessions
bump for chrome already baked in) as canonical git source. ArgoCD's
ServerSideApply syncPolicy + selfHeal will now keep the grid in lock
step with this file.

Resources captured:
  - Service selenium-hub (ClusterIP, internal traffic on 4444)
  - Service selenium-hub-external (LoadBalancer, MetalLB 10.0.56.208)
  - Deployment selenium-hub
  - Deployment selenium-node-chrome (replicas=1, SE_NODE_MAX_SESSIONS=2)
  - Deployment selenium-node-firefox (replicas=1, maxSessions=1)
  - Deployment selenium-node-edge (replicas=1, maxSessions=1)
  - IngressRoute selenium-hub (Traefik, selenium.iamworkin.lan)

No live behavior change — server-side dry-run confirms unchanged for
hub/firefox/ingressroute, "configured" for hub-external + 3 deploys
(default-field reordering only; SSA + field managers handle the diff).

# Selenium Grid 4 — RKE2 deployment
#
# Hub + chrome + firefox + edge browser nodes serving fleet-wide AAT runs from
# the GitHub Actions self-hosted runners. ArgoCD owns this namespace from
# 2026-05-25 (`infra-selenium` Application; previously these resources were
# orphan kubectl-applied since 2026-03-15).
#
# Endpoints:
# - Internal cluster: http://selenium-hub.selenium.svc.cluster.local:4444
# - LAN LoadBalancer (MetalLB): http://10.0.56.208:4444
# - Traefik public: https://selenium.iamworkin.lan
#
# Browser maxSessions:
# - chrome 2 (bumped from 1 on 2026-05-25 morning-routine — AAT-heavy
# Print.Web help-screenshots was the global bottleneck;
# see commit history for ops/runner-replica-rightsize)
# - firefox 1
# - edge 1
#
# Screenshots + video recording write to NFS via the chrome video sidecar.
# See: CLAUDE.md "Selenium Grid & Visual AAT Testing" + bluejay-infra ADR notes.
