…e builds Containers are identified by a fingerprint of their environment (image, apt mirror, proposed pocket, host uid/gid, build root) and named deterministically within LXD's 63-char limit, so persistent environments self-invalidate when any input changes. New build capabilities, configurable via CLI flags or debmagic.toml: --apt-mirror replaces the base image's apt sources with a managed deb822 file pointing at a given mirror (via scripts/mirror.py) --proposed enables the release's -proposed pocket --persistent keeps the build environment for reuse across invocations --incremental (binary builds) synchronizes changed source inputs while preserving build outputs, tracked by a source manifest --sign/--sign-key GPG-sign the resulting .changes/.dsc with debsign, always on the host since it needs the user's keyring --debug-symbols controls the automatic -dbgsym package via DEB_BUILD_OPTIONS --clean runs debian/rules clean before building Split 'debmagic build' into 'build binary' and 'build source' targets; source builds default to the bare driver since they need neither build-deps nor compilation.
add --source-sync (config key source_sync_mode) with three modes: - 'tracked' (default) stages git-tracked files including uncommitted changes and warns about untracked files left out - 'committed' fails on a dirty worktree - 'worktree' keeps staging everything not git-ignored. this makes it explicit which files end up in the build tree and in generated source packages. git submodules are skipped with a note, and both git modes fall back to 'worktree' with a warning outside a git worktree.
move source-tree staging and incremental sync into build/source.rs and the attach/detach socket server into build/attach.rs, leaving build/mod.rs with the build orchestration itself

many new features :)
lxd driver, apt-mirror + proposed, delegated signing, debug symbols, rules/clean support, source build sync modes (worktree/tracked/committed)
