Detailed Description

Phase-5a verification (collocated grid): the lid-driven cavity vs Ghia, Ghia & Shin (1982), Re=100 --
the canonical native-domain-BC benchmark. Three no-slip walls (-x,+x,-y) + a lid (+y) moving in +x,
quasi-2D (periodic z), no immersed solid. This exercises the collocated domain-BC machinery: cell-centered
reflection velocity ghosts (every component reflects about the boundary face), the explicit-reflection
diffusion smoother, and the Neumann phi wall ghost in the approximate projection.
