Lootable unit corpses (UNIT_DYNFLAG_LOOTABLE) now click-through over
blocking players, matching the existing behavior for interactable NPCs
and game objects. Adds isLootable() check to the interactable NPC test
and UNIT_DYNAMIC_FLAGS descriptor offset to shared offsets.
Also adds RELEASE_NOTES.md for tracking changes between releases, and
adds a checklist item in RELEASING.md to review it before publishing.
- dataassets module renamed to customassets everywhere (build flag,
source, DLL variant name, docs)
- Markers addon renamed to WorldMarkers (addon path, .toc, .lua,
Bindings.xml header, Lua globals, debug log prefix, mutex name)
- All 9 module mutexes now use WeirdUtils_ prefix to avoid
collisions with other DLLs in the same process
