hulthe 8fdac31160 Inject universal /slim/init instead of requiring container-specific setup
CI / build (pull_request) Successful in 13s
slim now works with any Containerfile by injecting distro-agnostic scripts
at build time:

- /slim/init: mounts special filesystems, configures networking (static
  QEMU slirp), sets up cgroup2, timezone, and rootless container prereqs.
  Parses slim.cmd=<base64> from the kernel cmdline for runtime overrides,
  otherwise execs /slim/exec.

- /slim/exec: generated from the image's CMD/ENTRYPOINT (via podman image
  inspect), overridable via --cmd at build and run time.

Changes:
- New src/inject.rs: inspect image config, infer command, generate
  /slim/exec script, inject /slim/ into mounted rootfs
- New src/scripts/slim-init.sh: the universal init script (include_str!)
- build.rs: rename --init to --cmd, inject scripts before packing,
  drop Meta::save, restructure to ensure unmount always runs
- qemu.rs: hardcode init=/slim/init, add --cmd (base64 on cmdline),
  drop Meta::load, add -no-reboot
- Remove src/meta.rs and meta.toml (no longer needed)
- Cargo.toml: add serde_json + base64, remove unused walkdir + cpio + toml
- Example Containerfiles simplified to plain FROM + CMD
- New example/test.sh for manual verification
- README updated for new workflow

marvin 37f537184c refactor: split main.rs into registry, build, and qemu modules
CI / build (pull_request) Successful in 10s
CI / build (push) Successful in 11s
main.rs keeps only the CLI definition and command dispatch:
- registry.rs: image-name validation + XDG registry path handling (tests)
- build.rs: podman mount/unmount, vmlinuz extraction, cpio/gzip initrd
- qemu.rs: direct-kernel-boot VM launch

No behavior change; cargo fmt/clippy/test pass, build/run paths
verified against the mock-vm image.
