xfy 6ccd0a173b render: bright-pass material + camera (bloom stage [2]) ...

Adds BrightPassMaterial + brightpass.wgsl: extracts luminance above a
soft-knee threshold from the HDR offscreen into a half-res Rgba16Float
target (bloom_0). Camera order -19 (after offscreen at -20). The brightpass
output is not yet composited (Task 6); this commit only adds the pass and
confirms it runs without crashing.
