perf: Go 1.26, multi-arch native build, BuildKit cache

- Upgrade Go 1.24 -> 1.26 in go.mod and Dockerfile
- Remove hardcoded GOOS/GOARCH for native multi-arch builds
- Add BuildKit cache mounts for go modules and build cache
- Bump Alpine 3.19 -> 3.21 in production stage
- Switch docker.yml to hanzoai reusable docker-build workflow
- Add .dockerignore to reduce build context
- Gitignore AI agent context files
