Bundle sizes are generated with rslib (Rspack). Package-root metrics preserve the historical report. Tracked subpath exports such as ./bundler are measured separately so ENV_TARGET-driven tree-shaking is visible. Bare imports are externalized to keep package-level sizes consistent, and assets are emitted as resources.

raven-actions/actionlint@v2 runs npm install internally which fails on pnpm workspace repos due to workspace:* protocol. Switch to direct binary download which has no npm dependency. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
