feat: add comprehensive build script for socket package

Create new build.mjs that:
- Builds bootstrap files for SEA and smol binaries
- Copies LICENSE, CHANGELOG.md, and logo images from repo root
- Updates package.json files array to include copied assets
- Replaces build-bootstrap.mjs with unified build approach

This ensures the socket package includes all necessary assets for distribution.
