Complete architecture rewrite. Each package now runs in its own Ruby::Box with constants resolved lazily at runtime via const_missing. Reads standard Packwerk package.yml files without requiring Packwerk.

Added

• Package isolation — each package runs in its own Ruby::Box; constants from undeclared dependencies and private constants raise NameError at runtime.
• Per-package gems — packages can declare their own gems.rb/Gemfile with independent gem versions; auto-require mirrors Bundler's default behaviour (respects require: false, require: 'path').
• Zeitwerk autoloading — constants discovered via Zeitwerk conventions; default autoload roots: lib/ and public/.
• Privacy enforcement — enforce_privacy, public_path, private_constants, and # pack_public: true file sigil.
• Boxwerk.package — returns a PackageContext in per-package boot.rb with name, root?, config, root_path, and autoloader.
• Boxwerk.global — returns a GlobalContext from any box context.
• Autoloader API — push_dir, collapse, ignore, setup on both PackageContext::Autoloader and GlobalContext::Autoloader; shared via AutoloaderMixin. push_dir and collapse auto-call setup so constants are available immediately in boot scripts.
• global/boot.rb — runs in the root box before package boxes; shared constants defined here are inherited by all packages.
• eager_load_global / eager_load_packages boxwerk.yml options.
• Package name normalization — leading ./ and trailing / stripped; packs/foo, ./packs/foo, and packs/foo/ are equivalent.
• CLI commands — exec, run, console, install, info.
• boxwerk install — installs gems for all packages; works on a fresh clone without pre-installed gems.
• boxwerk info — shows config, global context, and per-package autoload/collapse/ignore dirs (with eager-load status), enforcements, dependencies, gems, and boot script presence. Boots the application (RUBY_BOX=1 required).
• NameError hints — improved error messages like (defined in 'packs/baz', not a dependency of '.') in child package contexts.
• Circular dependency detection in boxwerk info tree output.
• collapse / ignore in boot.rb — collapses intermediate namespaces (e.g. Analytics::Formatters → Analytics::*); ignores dirs from autoloading.
• Missing lockfile warning — graceful message directing to boxwerk install when a Gemfile exists but no lockfile is found.
• Monkey patch isolation — patches defined in one package box are not visible in other packages or the root context.
• examples/complex and examples/minimal demonstrating all features.
• E2E test suite (74 tests) alongside unit tests (120 tests).
• GitHub Pages API documentation published from lib/ via RDoc.
