meteor-decomp: FINAL FANTASY XIV 1.23b client and network decompilation

meteor-decomp reconstructs functions and network behavior from five FINAL FANTASY XIV 1.23b Windows client executables. It combines byte-matching C++ work with Ghidra analysis of vtables, packet dispatch, Blowfish lobby encryption and resource-pack chunks; the author reports partial matching coverage and unresolved work.
