Claude 8d32d67f0e Color: Project Settings ▸ Working Gamma 2.2 / 2.4 with no working space, as in After Effects (#495) ...

After Effects' `app.project.workingGamma` (2.2 or 2.4, ignored with a working space) sets
the curve an unmanaged project uses: at 2.2 the piecewise sRGB curve, at 2.4 a pure 2.4
power curve. EffectCraft always used sRGB, so linear EXRs (Interpret As Linear Light) from
a 2.4 project came out darker in the shadows (0.18 → 0.461 instead of 0.490).

- `ProjectSettings::working_gamma` (default 2.2, serde default for old projects).
- The colour pipe's unmanaged curve is the Working Gamma's (sRGB, or Rec. 709's pure 2.4
  curve): Interpret As Linear Light encodes untagged footage with it and Blend Colors Using
  1.0 Gamma linearizes with it; it is part of the pipe's cache key. The GPU path takes the
  same conversions.
- `file.projectSettings {workingGamma: 2.2|2.4}` (other values are refused, as in AE),
  `app.project.workingGamma` in scripts and a Working gamma choice in Project Settings.

Test: render test with linear 0.051 / 0.18 / 0.5 footage (0.290 / 0.490 / 0.749 at 2.4,
0.250 / 0.461 / 0.735 at 2.2, the values measured in AE), linear blending at 2.4, a working
space ignoring the setting, and the cache key.
