feat: add passthrough hooks for 6 more InitGameState constructors (Groups F+G)

Group F (display objects):
- DisplayGfx__ConstructFull (0x563FC0): stdcall(5), RET 0x14
- DDDisplay__ConstructTextbox (0x4FAF00): stdcall(3), RET 0xC
- DDGame__InitWeaponPanel (0x567770): stdcall(1), RET 0x4

Group G (buffer/stream objects):
- BufferObject__Constructor (0x545FD0): stdcall(3), RET 0xC
- GameStateStream__Init (0x4FB490): stdcall(1), RET 0x4
- DisplayObject__Constructor (0x540440): stdcall(2), RET 0x8

All no-log passthroughs (heap allocation in logging clobbers registers).
All 6 named in Ghidra. Total: 12 stdcall + 7 pure Rust = 19 hooks on
InitGameState sub-functions.

Headful + headless replay tests PASS.
