Subject: [PATCH 1/2] demos: introduce DevModule + rename bin/app.php to
 bin/be.php

Each runnable demo (hello-world, medical-triage, user-registration,
order-processing) now wraps Becoming with a per-demo DevBecoming that
flushes the semantic log to var/log/<demo>.json in a finally block, so
failed runs are captured too. The dev-specific bindings are isolated
in DevModule (AppModule stays focused on the demo's own bindings).

A generated var/log/<demo>.json is checked in alongside each demo as
a reference transcript, readable without running the code.
