daedalus-v4l2{,-dkms}: 79256dc/6ffe92b -> 5d8b436 — revert parking design

Lock-step downgrade of both packages to the revert tip of
daedalus-v4l2 (PR #10 closed PRs #7 + #8).  After
0.1.0+r28+g79256dc-1 / 0.1.0+r30+g6ffe92b-1 landed in production,
mpv (--hwdec=vaapi-copy) failed pre-playing with "Unable to dequeue
buffer: Resource temporarily unavailable" because the daemon
parked CAPTURE buffers waiting for libavcodec's display-order
reorder, violating libva's V4L2 stateless 1:1 contract.  See
daedalus-v4l2#9 for the diagnostic, #10 for the revert PR.

DAEDALUS_PROTO_VERSION drops 1 → 0; install both .debs in the same
apt transaction.  Userspace ABI returns to the f0d4186-equivalent
behaviour, plus PR #4 (cosmetic H.264 menu controls).  The
daedalus-v4l2-dkms #64 multi-kernel postinst behaviour stays in
build-deb.sh.

Visible regression: H.264 B-frame streams in Firefox return to the
"2 1 4 3 6 5" pair-swap visual.  Proper fix (concurrent in-flight
requests in daemon + display-order reorder moved into libva-v4l2-
request-fourier) tracked at daedalus-v4l2#11.

daedalus-v4l2-dkms (0.1.0+r33+g5d8b436-1) bookworm trixie; urgency=medium
* Bump to 5d8b436 — reverts daedalus-v4l2 PRs #7 + #8. Kernel
module returns to the pre-#7 buf_done_and_job_finish completion
model: no src/dst lifecycle decoupling, no parked dst_bufs, no
1:1-contract violation against libva-v4l2-request-fourier
(closes daedalus-v4l2#9 + #10 as won't-fix at this layer; proper
fix tracked at daedalus-v4l2#11).
* Wire-protocol drops 1 → 0; lock-step install with daedalus-v4l2
0.1.0+r33+g5d8b436 REQUIRED.
* Carries forward the #64 multi-kernel postinst fix.
