Vite 8 (rolldown) changed buildStart to take (this, options), so the
test's one-arg call failed typecheck. Add an ambient declaration for the
fixture's virtual bgm modules so its entry typechecks in the editor.
Add a SerializedPackage type for the JSON the plugin emits, and tests
that assert the maps serialize to plain objects, that the packages module
returns every package, and that buildStart watches def files. Add a
second fixture package to exercise multi-package collection.
Rename the plugin's virtual modules to virtual:bgm/packages and
virtual:bgm/package/<id> so they read as plugin-provided modules rather
than real packages. Update the unit and build integration tests.
Move the bgm vite plugin into the package so it can be tested in
isolation from the web app. Serve each package as a JSON module,
serializing its maps, and verify resolution through a real vite build
against a self-contained fixture.
Parse yaml/json/toml and markdown code blocks into packages, expanding
$variants via typed-csv and collecting parts, surfaces, and setups by
include patterns. Ships zod validation, a vitest config, and 16 tests.
