Tracked ./bundler entry gzip: 556 B (no change)
Tracked ./bundler web bundle (gzip): 4.5 kB (no change)
Tracked ./bundler node bundle (gzip): 4.5 kB (no change)

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.

Could you please tell me what problem this PR is trying to solve? I see it seems will create remote types , but why not just download it ?
