Protocol Synchronization: Copies the "Single Source of Truth" constants (shared/constants.js) and the domain blacklist (shared/blacklist.js) from the root /shared directory into the extension/shared/ directory.
Artifact Generation: Compiles the extension into browser-specific bundles for Chrome and Firefox, located in the dist/ directory.

Usage

From the repository root, run:

node scripts/build-extension.js

Why this script exists

KoalaSync uses Vanilla JS in the extension to maintain zero runtime dependencies and maximum privacy. Since we don't use a bundler (like Webpack or Vite) inside the extension, this script serves as our lightweight "pre-build" step to ensure that the protocol constants remain synchronized between the extension and the relay server.
