Description

Expand scripts/bundle-size-report.mjs so bundle-size reporting captures target-aware output in addition to existing dist/entry metrics.

This PR:

  • keeps existing measurement and compare CLI flow intact
  • adds web/node bundle metrics (gzip + bytes) produced with rslib and ENV_TARGET
  • extends markdown compare output with separate sections for dist/entry vs target bundles
  • surfaces per-package bundle errors instead of silently dropping missing metrics

Scope

  • scripts/bundle-size-report.mjs only

Why split

This is the base PR in a stack so bundle-size behavior changes can be reviewed independently from sdk/runtime env changes.

Related PRs

Types of changes

  • Docs change / refactoring / dependency upgrade
  • New feature (non-breaking change which adds functionality)
  • Bug fix (non-breaking change which fixes an issue)

Test plan

Not re-run in this split operation. Validation is expected through CI on this PR.

Bundle sizes are generated with rslib (Rspack). Web/node bundles set ENV_TARGET and enable tree-shaking. Bare imports are externalized to keep sizes consistent with prior reporting, and assets are emitted as resources.
