Alps 8227l-demo Firmware: Update

Developer ergonomics and observability A well-crafted demo firmware goes beyond feature exposure: it surfaces debugging aids in a way that balances utility and safety. Verbose logs, interactive shells, and test endpoints are crucial for debugging, but they should be gated or modular so that integrators can selectively enable them. Structured logs, known telemetry points, and clear error codes make reproducing and diagnosing problems far easier. Additionally, example host-side tools or scripts that parse logs, flash images, and run sanity tests significantly lower the barrier to adoption.
