Description

Blocked by #2912

This issue is not trivial -- we need to prune all breaks that appear inside, because outside of a switch they produce invalid wgsl.
Alternatively, we could only fold simple switch statements, e.g. ones not introducing any blocks inside.

Research direction

Start by resolving the dependency on issue #2912, then inspect the comptime switch-folding path and the generated WGSL around switch breaks. Done means folded switches no longer leave invalid breaks in WGSL, or the implementation explicitly limits folding to switches without nested blocks.
