Detailed Description

The ADT round-trip driver: the write -> parse -> write-again stability compare of one terrain tile (ADT is not byte-perfect — alpha maps are re-encoded and the MHDR/MCIN/MCNK offset tables re-derived), modeled on tests/integration/test_adt_roundtrip.cpp with the reflection diff replaced by the write-stability byte compare and returned outcomes in place of Catch2 assertions.

The on-disk alpha-map bit depth is a per-MAP property (the WDT MPHD big-alpha flags) that wowlib does not resolve itself; every call re-derives it by reading the map's own WDT next to the tile ("<dir>/<map>.wdt" from the tile's parent directory). Nothing is cached — calls stay independent, and the sweep feeds tiles map by map anyway.
