- Introduce support for bundled 'builtin' extensions in ExtensionManager
- Migrate conductor extension to packages/core/src/extensions/builtin/conductor
- Add automatic migration logic to cleanup manual conductor installations
- Make extension versioning optional for built-ins, defaulting to CLI version
- Update build and bundle scripts to include builtin extensions
- Enhance documentation to highlight conductor as a core feature
- Converted scripts/copy_files.cjs to use ES module syntax (renaming to copy_files.js).
- This change aligns with the project's preference for ES modules over CommonJS for better modernity and future-proofing.
- Updated eslint.config.js to remove the .cjs override.
- Adjusted scripts/build_package.sh to call the new .js file.
