v0.1.32

v0.1.32 — fix the brightness-support install

apt was succeeding while the running process still couldn't import the
library. The installer now restarts the service to pick it up (guarded by
the camera lock), but only after a fresh interpreter proves a restart will
actually help — a genuinely broken library reports its real error instead.

Installer output now goes to the journal, so a failed install is visible in
View logs. /api/diag reports free disk. The brightness toggle can always be
switched off, even when the library is missing.

v0.1.31

v0.1.31 — automatic brightness correction

Corrects a dark/bright capture in the pixels instead of re-shooting it:
metered frames are pulled onto a target with a bounded gamma curve on a
background worker, keeping the untouched original for compare/undo and
shipping it in the download zip. RAW is never touched.

Needs python3-pil. New SD-card images include it; an existing appliance
can install it from Setup ("Install brightness support") with no SSH.

Not yet exercised on the Pi — first run is a bring-up.
