Managing Dart Concurrency and Isolates

Explains Dart's single-threaded event loop model and provides a decision matrix for async/await vs. Isolates: use async/await for I/O-bound or fast (<16ms) operations, Isolate.run() for one-off heavy computation, and Isolate.spawn() with SendPort/ReceivePort for long-lived background workers. Includes workflows for standard async UI with FutureBuilder, offloading JSON parsing, and establishing persistent worker isolates.
