RealtaNuaandClaude Opus 5.5 18e3070d4c fix(render): glass looks the same wherever a render cuts it ...

The glass light falls off with the distance to the edge, read past
`depth` (up to ~3 × depth at full splay), but the coverage window around
a cut layer was only `depth + 2` wide. With frost and refraction at 0
the backdrop margin is 0 too, so a band or canvas patch edge running
through the pane changed the light near it: up to 12 levels between a
banded and a whole render.

The window now covers the light's reach (where it falls under half a
level, clamped at 0 and capped at 512 px) plus the span the normals are
smoothed over, and past that reach the light is 0 instead of whatever
the window happened to hold.

Tests: a cut 50–80 px inside the pane equals the whole render byte for
byte (fails on main by 12 levels); light_reach edge cases. Adds an
ignored release timing test (glass_bench_tests).
