test0r 1bd11eaf27 daedalus-v4l2{,-dkms}: f04d700 -> f55b2cd (UAF lifetime fix)
Bumps all 4 daedalus packages (arch + debian × userspace + dkms)
to pick up daedalus-v4l2 f55b2cd: "kernel: media_request_get/put
around inf->req (UAF safety)".

Closes the SHIP-WITH-EYES-OPEN concern Sonnet flagged in the
pre-deployment review — without explicit media_request_get on
capture + media_request_put on completion, a concurrent
MEDIA_IOC_REQUEST_REINIT or process-kill triggering
buf_request_complete from the cancel path could drop vb2's
reference before our completion handler ran, leaving inf->req
dangling through v4l2_ctrl_request_complete + buf_done.

Matches the cedrus / rkvdec refcount pattern.  No protocol
change, no API change, no consumer-side adjustment required.
Same byte-exact output verified on hertz post-fix (libva path:
match; standalone test_m2m_stream: 30/30 frames).

test0r 6de7268b49 arch/daedalus-v4l2: new package — userspace daemon + tools
PKGBUILD pinning daedalus-v4l2 @ f04d700 (Phase 8.13 close).

Installs:
- /usr/bin/daedalus_v4l2_daemon — the FFmpeg-backed decode daemon
- /usr/libexec/daedalus-v4l2/{test_chardev_pingpong,test_m2m_decode,
  test_m2m_stream} — verification harnesses
- /usr/include/daedalus_v4l2_proto.h — shared kernel↔daemon wire
  protocol (for third-party chardev clients)
- /usr/share/doc/daedalus-v4l2/ — README + Phase 8.x closure docs

Runtime deps: ffmpeg (libavformat/libavcodec/libavutil dlopen'd
at runtime per Option γ — daemon binary is link-clean from
FFmpeg), libdrm.

optdepends:
- daedalus-v4l2-dkms: companion kernel module
- libva-v4l2-request-fourier: VAAPI consumer routing through us

Sibling Debian package: debian/daedalus-v4l2/
