face::ExpressionsRegistry Class

Detailed Description

Phase 8 migration: backed by eval::v2 (libeval v2 — the GLSL 4.60 desktop subset). Each registered expression becomes a v2 output; `dt` (frame delta) is a v2 input. Calling step(dt) sets `dt` and re-runs the compiled program.

Old v1 API (`QSharedPointer<CompiledExpression>` return, `ExpressionContext` reuse) is gone — the v1 surface was only used internally by face::Project::stepExpressions; lookupExpression has no remaining callers and is dropped.
