filmcraft-mxf gains a streaming writer (ST 377-1 partitions, primer, header
metadata, VBR index segments with temporal offsets, RIP; ST 378 OP1a
frame wrapping, ST 390 OP-Atom clip wrapping) for VC-3, ProRes, AVC byte
stream and PCM with start timecode and caller-supplied package UMIDs, plus
write_opatom_pcm. filmcraft-export adds mxf-op1a / mxf-opatom formats
(DNxHR, ProRes or H.264 + PCM; OP-Atom writes one mono file per channel),
presets, the engine mxfVideoCodec parameter and CLI .mxf inference.
Tests read our files back and check them against ffprobe / ffmpeg.

Premiere's AAF and OMF export options: embedded or separate WAV/AIFF audio,
sample rate and bit depth, trim with handles, rendered clip effects, breakout
to mono, AAF video mixdown and linked media; AAF/OMF import writes embedded
audio next to the document and links it.

Shared mob-style composition model; AAF objects in structured storage over
filmcraft-cfb; OMF objects in a Bento container; embedded / consolidated audio
supplied by the caller (essence::audio_needs, MediaOptions).

Interleaved before/after bench (decode, playback incl. 1/4 and draft cases,
4K cold seeks) and decoder cycle counts in docs/performance.md; threading,
draft mode and 4K numbers in crates/h264/README.md; bench cases in
docs/testing.md.

The column pass and the add/clip of idct4/idct8 work on whole rows so they
vectorise (same integer steps in the spec's row-then-column order; checked
against the per-column formulation on random blocks). Docs: draft decoding in
architecture.md and perf.stats fields in control-protocol.md.

Settings > Playback > Draft decoding (off by default): the Program monitor
asks for draft frames only while playing at 1/2 resolution or lower
(FrameKey::draft, filmcraft_media::cancel::with_draft). The GOP cache runs
the decoder in draft mode for those requests and serves draft frames to draft
requests only, so paused frames, renders and exports always get exact
pictures (codecs test: exports after draft playback match ffmpeg). Draft
plans hand the GPU box-decimated YUV planes at the drawn size. perf.stats
reports draft frames, H.264 threads and the preference; the bench gains
2160p quarter and draft playback cases.

Decoder::set_draft: non-reference pictures skip the deblocking filter and are
flagged Picture::draft; all other pictures stay bit-exact (conformance test,
single- and frame-threaded). Conformance fixtures now also decode with 3
threads. Decoder::threads / default_threads for perf.stats.

Deblocking filters all lines of an edge at once with per-lane masks (bit-exact
with the per-line filter, checked on random edges); CABAC decode_decision /
bypass select instead of branching. 4K single-thread CPU -19 %, output
identical to ffmpeg.

Adds ~115 keyboard-only commands from Premiere's default keyboard (engine:
filmcraft_engine::keyboard, UI: panels::keyboard): edit-point navigation on
targeted/any track, go to selected clip start/end, reveal nested sequence,
select clip at playhead/next/previous, extend previous/next edit to playhead,
nudge/slip/slide clip selection, target and source-patch toggles, clip volume
keys, audio scrubbing toggle, text size/leading/alignment, object nudge,
Export Frame, poster frames, frame maximize/full screen/panel cycling, monitor
zoom, track heights, Project and Text panel keyboard navigation, play to Out.
Existing commands that lacked their Premiere key are added to the table;
panel-scoped keys live in PREMIERE_PANEL. docs/keyboard.md lists the 39
skipped shortcuts with reasons. Tests: table integrity (no dangling ids, no
duplicate keys per scope, no conflicts), engine behaviour with undo, headless
key presses.
