WORKAROUND:
a) From the project root, run uv run adk web . --host 127.0.0.1 --port 8080 --allow_origins "http://127.0.0.1:8080"
b) Once the server is listening, run agents-cli run "Hello" --url http://127.0.0.1:8080 --mode adk from another terminal.
