feat: Convert protocol-registry to ESM and improve build system

- Convert all protocol-registry files from CommonJS to ESM
- Fix all CommonJS warnings in build process
- Improve esbuild configuration with advanced optimization
- Add bundle analysis and development build modes
- Fix all linting issues (eqeqeq, unused variables, import order)
- Update build scripts and configuration
- Ensure all tests pass (32/32 tests passing)
- Version bump to 1.2.0

Breaking changes:
- All protocol-registry modules now use ESM syntax
- esbuild.config.js renamed to esbuild.config.cjs
