chore: initial infrastructure scaffold

Kustomize base + overlays for the full Sunbeam k3s stack:
- base/mesh      — Linkerd edge (crds + control-plane + viz)
- base/ingress   — custom Pingora edge proxy
- base/ory       — Kratos 0.60.1 + Hydra 0.60.1 + login-ui
- base/data      — CloudNativePG 0.27.1, Valkey 8, OpenSearch 2
- base/storage   — SeaweedFS master + volume + filer (S3 on :8333)
- base/lasuite   — Hive sync daemon + La Suite app placeholders
- base/media     — LiveKit livekit-server 1.9.0
- base/devtools  — Gitea 12.5.0 (external PG + Valkey)
overlays/local   — sslip.io domain, mkcert TLS, Lima hostPort
overlays/production — stub (TODOs for sunbeam.pt values)
scripts/         — local-up/down/certs/urls helpers
justfile         — up / down / certs / urls targets

+# NOTE: Linkerd stable releases moved behind a commercial paywall in Feb 2024.
+# As of 2.15, stable artifacts are Buoyant Enterprise for Linkerd (BEL) only.
+# The free channel is "edge" (weekly date-versioned builds).
+#
+# For local dev: local-up.sh installs Linkerd via the CLI directly:
+#   linkerd install --crds | kubectl apply -f -
+#   linkerd install | kubectl apply -f -
+# which is simpler and uses whatever edge version the CLI was built against.
+#
+# The blocks below are the production Helm path (edge channel, pinned dates).
+# To use stable BEL, change repo to https://helm.linkerd.io/stable with a
+# valid BEL entitlement secret and use versions 1.8.0 / 1.16.11 / 30.12.11.
