research: full acclient.exe decompilation — 22,225 functions, 688K lines

Complete decompilation of the retail Asheron's Call client using
Ghidra 12.0.4 + pyghidra headless. 22,225 of 22,226 functions
successfully decompiled in 75 seconds.

Output: docs/research/decompiled/ (54 files, 688,567 lines of C)

Key findings already identified:
- CLandBlockStruct::ConstructPolygons at chunk_00530000.c:2270
  (split direction formula with 0x0CCAC033 constants)
- Motion command handlers at chunk_00510000.c (0x45000005 etc)
- Motion interpreter at chunk_00520000.c
- Portal space UI at chunk_004D0000.c and chunk_00560000.c

Next: identify CPhysicsObj, CMotionInterp, collision, and movement
functions by cross-referencing against ACE's C# port.
