fix(agc): look up cached draws at the fixed pixel push slot

With graphics pipeline libraries a draw places the pixel shader's push
constants at the fixed fragment slot (Graphics::StagePushOffset) and the
draw cache records that offset, but lookupDraw still expected the stacked
offset after the vertex shader's push bytes. Every pixel stage then missed
as a layout mismatch, so no cached draw or draw recipe was reused and each
draw was captured and materialized again.
