fix: repair frontend package entrypoints and declarations

Fix missing package entrypoints and empty declarations while preserving existing ESM deep imports. Add separate CommonJS output and rebuild both before publication.

Validation: both builds, lint, 49 tests, and packed CommonJS, TypeScript and Chromium consumers passed. Publication and dist-tag changes are outside this PR.
