Pull request overview

Exposes the in-cluster git-server via a Gateway API HTTPRoute at git.<domainSuffix>, attached to the shared platform HTTPS Gateway listener. Follows the same pattern used by Argo CD / Keycloak (chart-native HTTPRoute + Otomi values wiring via the shared routes.gotmpl snippet).

Changes:

• Adds a new templates/httproute.yaml and httproute.* defaults to the git-server chart.
• Wires the route in values/git-server/git-server.gotmpl using shared parentRefs/annotations from helmfile.d/snippets/routes.gotmpl, gated by apps.git-server.createHttpRoute.
• Adds createHttpRoute to values-schema.yaml and defaults it to true in helmfile.d/snippets/defaults.yaml.
