Overview

Walks Bundler.load.specs to find gems that declare themselves as Lilac packages via metadata["lilac_package"] == "true".

Each entry is described by Discovered (gem name, version, mrblib source files). Builder feeds the source files into PackageBuild#compile_to_bytes at build time and stages the produced .mrb under dist/packages/.

If Bundler isn't loaded (e.g. lilac-cli is being run from a context without a Gemfile), discovery silently returns an empty list. Users who want explicit control set c.packages = [...paths] in lilac.config.rb, which goes through a different code path and bypasses discovery.
