Implement automatic rebuild and browser reload during development:
- File watcher monitors .go files for changes with configurable extensions
- Builder compiles Go source to WASM on file changes
- LiveReload WebSocket server notifies connected browsers to reload
- DevServer combines all components for easy development setup
- HTML injection adds reload script automatically
Usage:
dev := host.NewDevServer("public", "index.html", ".", "public/app.wasm")
dev.ListenAndServe(":8080")
Closes #9
