Rust/clippy 1.99 added `chunks_exact_to_as_chunks` and tightened
`needless_late_init` and `drain_collect`, failing `clippy -D warnings`
on main.
- `chunks_exact(N)` / `chunks_exact_mut(N)` with a constant N become
`as_chunks::<N>()` / `as_chunks_mut::<N>()` (fixed-size arrays, so
several byte reads drop their per-element indexing). relink's
fingerprint uses the `(chunks, remainder)` split; its hash output is
unchanged.
- Late-initialised `let`s in ac3 bit allocation and opus CELT
bands/rate become `let x = if/match …`.
- `dpb.drain(..).collect()` becomes `std::mem::take(&mut dpb)`.
No behaviour change; `cargo xtask ci` passes.

Sub-pixel filter passes run over fixed block widths; frame / region planes are recycled
through a bounded pool (zeroed on reuse) instead of fresh calloc / munmap per frame; the
palette mode-info arrays (40 bytes per 4x4) exist only when screen content tools are allowed;
CDF adaptation is branch-free. Draft mode skips deblocking, CDEF and loop restoration of shown
frames that refresh no reference slot. Media-stack test: VP9 / HEVC / AV1 draft playback only
reaches draft requests, and an export afterwards is bit-exact with ffmpeg.

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.
