Details 
- Gitea Actions CI pipeline: Go tests, build, shellcheck on push/PR
- Gitea Actions release pipeline: full build + artifact upload on version tags
- OCI container image builder for registry-based OS distribution
- Zero-dependency Prometheus metrics endpoint (kubesolo_os_info, boot,
  memory, update status) with 10 tests
- USB provisioning tool for air-gapped deployments with cloud-init injection
- ARM64 cross-compilation support (TARGET_ARCH env var + build-cross.sh)
- Updated build scripts to accept TARGET_ARCH for both amd64 and arm64
- New Makefile targets: oci-image, build-cross

49a37e30e8 feat: add production hardening — Ed25519 signing, Portainer Edge, SSH extension (Phase 4) 
Image signing:
- Ed25519 sign/verify package (pure Go stdlib, zero deps)
- genkey and sign CLI subcommands for build system
- Optional --pubkey flag for verifying updates on apply
- Signature URLs in update metadata (latest.json)

Portainer Edge Agent:
- cloud-init portainer.go module writes K8s manifest
- Auto-deploys Edge Agent when portainer.edge-agent.enabled
- Full RBAC (ServiceAccount, ClusterRoleBinding, Deployment)
- 5 Portainer tests in portainer_test.go

Production tooling:
- SSH debug extension builder (hack/build-ssh-extension.sh)
- Boot performance benchmark (test/benchmark/bench-boot.sh)
- Resource usage benchmark (test/benchmark/bench-resources.sh)
- Deployment guide (docs/deployment-guide.md)

Test results: 50 update agent tests + 22 cloud-init tests passing.

8d25e1890e feat: add A/B partition updates with GRUB and Go update agent (Phase 3) 
Implement atomic OS updates via A/B partition scheme with automatic
rollback. GRUB bootloader manages slot selection with a 3-attempt
boot counter that auto-rolls back on repeated health check failures.

GRUB boot config:
- A/B slot selection with boot_counter/boot_success env vars
- Automatic rollback when counter reaches 0 (3 failed boots)
- Debug, emergency shell, and manual slot-switch menu entries

Disk image (refactored):
- 4-partition GPT layout: EFI + System A + System B + Data
- GRUB EFI/BIOS installation with graceful fallbacks
- Both system partitions populated during image creation

Update agent (Go, zero external deps):
- pkg/grubenv: read/write GRUB env vars (grub-editenv + manual fallback)
- pkg/partition: find/mount/write system partitions by label
- pkg/image: HTTP download with SHA256 verification
- pkg/health: post-boot checks (containerd, API server, node Ready)
- 6 CLI commands: check, apply, activate, rollback, healthcheck, status
- 37 unit tests across all 4 packages

Deployment:
- K8s CronJob for automatic update checks (every 6 hours)
- ConfigMap for update server URL
- Health check Job for post-boot verification

Build pipeline:
- build-update-agent.sh compiles static Linux binary (~5.9 MB)
- inject-kubesolo.sh includes update agent in initramfs
- Makefile: build-update-agent, test-update-agent, test-update targets
