Augustus Nguyen 4bcfaae325 Add Chainguard registry (cgr.dev) login support
Implement native OIDC-based authentication for Chainguard's container
registry, following the same pattern as the existing AWS ECR integration.

When registry is set to cgr.dev, the action automatically exchanges a
GitHub Actions OIDC token with Chainguard's STS endpoint for a short-lived
registry credential, removing the need for chainctl or long-lived pull tokens.

New inputs: chainguard (auto/true/false), chainguard-identity.
