Blender 5 logs through CLOG, prefixing every line with elapsed time and a
category ("00:02.954 render | Saved: '...'"), and reports errors as
"ERROR ..." instead of "Error: ...". The parser anchored on "Saved:" at the
start of the line, so it counted no frames from a render that wrote all of
them and the job failed as "saved no frames". Progress (Fra:) and error
detection were dead on 5.x for the same reason.
The prefix is now stripped before matching; 4.x output parses as before.
Warnings no longer count as errors: add-ons print them on every launch and
one would otherwise be reported as the reason a render failed. A run that
saves nothing now reports Blender's own error when there is one.
Verified on the real DH2 test.blend under Blender 5.2: the 1.6.2 parser
counts 0 of 3 saved frames, this one counts 3.
Bump worker to 1.6.3.

Blender renders failed with "produced no output for 600s" on every
attempt while rendering perfectly well.
Two causes, both mine. BeginOutputReadLine raises an event per newline,
and Blender writes its render status with a carriage return so it
overwrites one line in place — a frame taking longer than the stall
timeout emits no newline for its whole duration. stdout is now read as a
character stream with CR and LF both ending a line.
The watchdog was also stricter than its own message: it only accepted a
recognised Fra:/Saved: line as a sign of life, so any output we were not
parsing counted as silence. Any output now proves Blender is alive, which
is what "produced no output" is asking; finished frames still drive
progress, since a single frame emits hundreds of status updates.
Also passes -noaudio: a render node has no sound device, and initialising
audio under a session-less service account is a known way to hang.
Covered by tests over a realistic stdout chunk where progress is
CR-separated and only the saved lines end in LF — newline-only splitting
yields one unusable blob and no progress at all.
Worker 1.5.1.
