Restructure the QCOW2 build pipeline so the target filesystem is created
and mounted before Phase 1, allowing rootfs population directly into it.
This removes the wasteful and fragile copy_rootfs step that was the source
of merged-/usr symlink breakage and fixes the ZFS shadow-mount bug where
the BE dataset was mounted over the staging root.
New flow: Phase 2 prepare → Phase 1 populate → Phase 2 finalize → cleanup.
OCI/Artifact targets are unchanged.

- Extend spec-parser schema with distro, AptMirror, filesystem, and
push-to fields for Ubuntu image support
- Add debootstrap/apt tool wrappers and Phase 1 distro dispatch
(OmniOS IPS vs Ubuntu apt)
- Add ext4+GPT+EFI QCOW2 build path alongside existing ZFS pipeline
- Add partition tools (sgdisk, mkfs) and loopback partprobe support
- Add ORAS-compatible OCI artifact push/pull for QCOW2 files with
custom media types (vnd.cloudnebula.qcow2)
- Add --artifact flag to forger push command
- Add auto-push from Phase 2 when target has push-to set
- Add omnios-rust-ci and ubuntu-rust-ci KDL image specs
- Update inspect command to display new fields

Standalone workspace with 4 crates for building optimized OS images
and publishing to OCI registries:
- spec-parser: KDL image spec parsing with include resolution and
profile-based conditional filtering
- forge-oci: OCI image creation (tar layers, manifests, Image Layout)
and registry push via oci-client
- forge-engine: Build pipeline with Phase 1 (rootfs assembly via native
package managers with -R) and Phase 2 (QCOW2/OCI/artifact targets),
plus dyn-compatible ToolRunner trait for external tool execution
- forger: CLI binary with build, validate, inspect, push, and targets
commands
Ported KDL specs and overlay files from the vm-manager prototype.
