Summary

• add a Chrome Web Store packaging pipeline that builds a store-safe manifest and zip artifact (bun run build:cws)
• update the extension runtime to request optional permissions on click and gracefully degrade when native messaging/site access/debugger/download permissions are not granted
• add maintainer docs and templates for submission, privacy disclosures, and listing copy

Testing

• node --check extension/background.js
• node --check bin/broker.cjs && node --check bin/native-host.cjs
• bun run build
• bun run build:cws
• Chrome pack validation on generated store staging extension
• Chrome MCP navigation checks and screenshots for extensions page + CWS pages
