Detailed Description

Unit & provenance metadata written as ;; header comments.

The writer does NOT perform any unit conversion — values are written in whatever unit the caller's mesh already carries (the project CRS linear unit, by convention aligned with the SWMM FLOW_UNITS). The metadata is purely descriptive so the reader / engine can branch on it.

Engine contract (today): [2D_VERTICES] XY is in the project's length unit (feet for US flow units, metres otherwise). Engine multiplies by 0.3048 in SurfaceRouter2D::initialize when the project is US. When the file declares ;; UNITS: SI (m) and the engine has been updated to honour it, the engine skips that multiplication.
