render: the debug-only quantisation check uses debug_assert! instead of panic!. gpu: the
test-only panic on a wgpu validation error is cfg(test) with a narrow allow, and release
builds only log. Test-only unreachable!() calls become panic!(). Denies the panic lints in both
crates.

8/16 bpc no longer re-quantises the whole comp after every layer: 2D layers
report the canvas region they can change (transformed buffer bounds plus the
resampling margin; stencil modes, motion blur, perspective, styles,
adjustment and 3D runs fall back to the full canvas), and only that region
is quantised. A quantised buffer placed pixel-exactly (integer translation,
Normal, 100%) over a blank canvas needs nothing; invisible layers need
nothing; collapsed precomps quantise per nested layer. The redundant final
comp pass is skipped unless the comp is re-encoded. Solids are filled with a
pre-quantised colour and skip the source pass unless masked. Row-parallel
vectorisable kernel. Debug builds verify every pixel outside the region is
already quantised (whole workspace test suite run with 8 bpc forced: no
violations).

8/16 bpc projects clamp and quantise layer pixels after source/masks and
every effect, and the comp after every layer (16 bpc = 0..32768); 32 bpc
keeps over-range values. Blend modes without HDR support clamp their inputs
in 32 bpc. Working space (sRGB, Rec. 709, Rec. 2020, Display P3; matrices
derived from the published primaries), footage colour profiles from stream
metadata or Interpret Footage, Linearize Working Space and Blend Colors Using
1.0 Gamma. Layer cache keys include the colour settings. Project panel depth
button: click cycles, Alt-click opens Project Settings.
