Detailed Description

Build the FV cell/face mesh from a SimulationContext.

Runs once at Router::init. The mesh is INTERNAL numerical discretization — it creates no named objects and is invisible to topology (plan §3.2). Virtual junctions are consumed here: their two conduit chains are concatenated into one continuous face graph, so mass and momentum flux continuity across them become properties of the scheme rather than a special treatment.
