Pull request overview
Fixes a mismatch between documented and actual buildStart hook behavior by exposing the input plugin list (plugins) on NormalizedInputOptions, enabling plugin-to-plugin communication during build start.
Changes:
- Expose
plugins: RolldownPlugin[]onNormalizedInputOptionsand implement it via a lazy getter. - Thread normalized input plugins through bundler option creation into
PluginContextDatasobuildStartreceives them. - Add a regression test ensuring
buildStartsees input plugins (and not output plugins).
