fingerprintd — the daemon shell.

Nothing here talks to hardware yet. The core (Fingerprintd:Sfs and the modules
that follow it) is being ported from the fp6 harness one wire format at a time,
each landing with tests that run without a phone; this entry point exists so
the executable target builds alongside them and so the version constant that
gates a package publish has a home.

What this will own, and why it has to be one long-lived process:

  * the sensor rail (gpio29), reset (gpio74) and IRQ (gpio75) — one sensor
    reset buys exactly one trustlet init, so whatever powers the sensor must
    also hold the session;
  * the QTEE session on /dev/tee0: client env, the QSEECOM-compat loader, and
    the focal64 trustlet, loaded once;
  * the storage listeners QTEE calls back into — gpfile 0x7000 and RPMB
    0x2000 — served from a supplicant thread that must outlive every request,
    because QTEE's listener table is global and an id is taken for as long as
    the registration is held;
  * net.reactivated.Fprint, so pam_fprintd and the desktop need no changes.
