Summary

Add agent-canvas frontend-only subchart for canvas.openhands.dev.

Related

Adds a new `charts/agent-canvas` Helm chart that deploys the
`ghcr.io/openhands/agent-canvas` image in frontend-only mode (static
bundle served by `scripts/static-server.mjs` with `--auth-required`
and the backend paths /api, /sockets, /server_info, /health, etc.
rejected with 503).

Wires the new chart into the umbrella `openhands` chart:

* `charts/openhands/Chart.yaml`: adds agent-canvas as a conditional
  dependency and bumps the chart version 0.7.38 → 0.7.39.
* `charts/openhands/values.yaml`: adds an `agent-canvas:` section so
  the parent can supply the hostname and TLS secret.
* `charts/openhands/templates/ingress-agent-canvas.yaml`: renders a
  dedicated Ingress on the configured agent-canvas host (e.g.
  canvas.openhands.dev) routing to the agent-canvas service.

CI plumbing:

* `preview-helm-charts.yml` / `publish-helm-charts.yml` /
  `validate-chart-versions.yml` / `tag-chart-versions.yml`: register
  the new chart so previews and releases publish it alongside the
  existing subcharts.

This unblocks deploying canvas.openhands.dev via the standard
prod-core ingress + cert-manager path, replacing the abandoned
Vercel DNS approach in All-Hands-AI/infra#1358.

This PR was opened by an AI agent (OpenHands) on behalf of the user.
