**Router Generation Fixes:**
- Fix router.js parsing (was looking for non-existent router.map.js)
- Parse Router.map(function() {...}) structure correctly
- Fix console route detection (check for path: '/' config)
- Fix function expression location (3rd arg after path config)
- Fix root extensions to use this.mount() not router.mount()
**File Watching:**
- Add chokidar to watch extension.js files in development
- Regenerate shims and loaders when extension.js changes
- Cache discovered extensions for regeneration
- Only watch in development mode
**Issues Fixed:**
1. Router.js now properly contains engine mounts
2. Extension.js changes trigger automatic regeneration
