Erich Blume 2985007430 Add native Dagger build for external-secrets (container.py)
Localizes external-secrets off ghcr.io: clones the forge mirror at v2.2.0
and builds the single all_providers static Go binary, faithful to upstream's
`make build`. ENTRYPOINT is the binary so the controller/webhook/cert-controller
Deployments can select their role via args.

"""External Secrets Operator — native Dagger build.
Two-stage build: Go binary (all providers), Alpine runtime.
Source cloned from forge mirror.
A single binary serves as the controller, webhook, and cert-controller; the
Deployments select the role via a subcommand passed in `args:`, so the image
ENTRYPOINT must be the binary itself (matching upstream's distroless image).
