- spec-parser: merge_include now merges repos, variants, certs, incorporation
- forge-engine: auto-increment UID/GID from existing passwd/group files
- forge-engine: replace shell-based APT source addition with direct file write
- forge-engine/forge-oci: OS field is now distro-aware (solaris vs linux)
- forge-engine: apply owner/group via lchown on file/dir/symlink overlays
- forge-oci: diff_ids now use uncompressed tar digests per OCI image spec
- forge-oci: track real uncompressed_size instead of hardcoded 0
- forge-engine/forge-builder: use spec metadata version instead of "latest"
Introduce the forge-builder crate that automatically delegates builds to
an ephemeral VM when the host can't build locally (e.g., QCOW2 targets
without root, or OmniOS images on Linux). The builder detects these
conditions, spins up a VM via vm-manager with user-mode networking,
uploads inputs, streams the remote build output, and retrieves artifacts.
Key changes:
- New forge-builder crate with detection, binary resolution, VM lifecycle
management, file transfer, and miette diagnostic errors
- BuilderNode added to spec-parser schema for per-spec VM config
- --local and --use-builder CLI flags on the build command
- Feature-gated (default on) integration in forger CLI
- Fix ext4 QCOW2 grub-install failure by using absolute paths in chroot
- Improve debootstrap to pass --components and write full sources.list

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.
