Both daemons previously produced no Info-level output on successful start,
making it impossible to confirm from the boot log whether ps2d and inputd
were actually alive. The kernel serial log shows no [INFO] ps2d: or [INFO]
inputd: lines during normal boot, leading operators to assume the input
stack was dead when in fact it was working.
This adds two log::info!() calls:
- ps2d main.rs: after daemon.ready(), log that ps2d has registered
its ProducerHandle and is listening on serio/0 (keyboard) and
serio/1 (mouse).
- inputd main.rs: after setup_logging, log that inputd has registered
scheme:input and is waiting for handles.
These are emitted only on the successful startup path; existing
.error!()/.warn!() calls continue to surface real failures. No behavior
change; no functional effect on input handling.
