Per-frame entity and playerState blocks are compressed with LZ4
when svdemo_compress is set (default: 1). The block format writes
[original_size][compressed_size][data] — compressed_size=0 means
uncompressed. Playback auto-detects based on header flags.
Demo format bumped to version 2 with SVDEMO_FLAG_COMPRESSED flag.
Version 1 (uncompressed) demos are no longer compatible.
Uses the lz4.c/lz4.h library already in the server code directory.

Records full entity state array each server frame, enabling
free-camera demo playback from any viewpoint.
Recording:
- svdemo_record <name> / svdemo_stop
- Captures entityState_t + PVS fields (svFlags, linked,
currentOrigin, absmin, absmax) for all active entities
- Records configstring changes per frame
- File format: svdemos/<name>.svdm
Playback:
- svdemo_play <name>
- Loads map with maxclients=64, reserves recorded player slots
(CS_ZOMBIE with safe rate/timing) so spectator gets a high slot
- Injects recorded entities into sv.gentities each frame with
SV_LinkEntity for PVS visibility
- Re-applies demo configstrings (CS_PLAYERS etc.) after map load,
skipping CS_SERVERINFO/CS_SYSTEMINFO to avoid latch restarts
- Game module runs in demo mode (sv_demoplaying cvar): G_RunFrame
only processes spectator movement, skips all entity logic
- Spectator forced to TEAM_SPECTATOR on connect (ClientBegin)

- Rename output binary from quake3.exe to quake3live.exe across all configurations
- Add DLL_ONLY define to Release TA and Debug TA configs to force native DLL loading
(VM_CallCompiled was a stub returning 0, causing "ui version 0" errors)
- Default fs_game to "missionpack" so the engine loads from workdir/missionpack/
- Add AfterBuild copy for ui.vcxproj to deploy uix86.dll to workdir
- Fix .gitignore: add Debug_TA/, remove *.exe/*.dll/*.lib/*.map patterns that were
hiding real SDK tools in code/win32/mod-sdk-setup/bin/
- Remove q3_ui project from solution (not used in TA builds)
- Increase hunk/zone memory defaults for modern systems

Add unconditional ItemDefinitionGroup in quake3.vcxproj to define DLL_ONLY
for all configurations, disabling QVM interpreter/JIT in favour of DLLs.
Fix vm_x86.c: VM_Compile was outside the #ifndef DLL_ONLY guard while
VM_CallCompiled was inside it, causing a duplicate symbol link error.
Extend the guard to cover VM_Compile as well.

- Use DirectInput8Create() instead of dynamic dinput.dll loading
- Switch to LPDIRECTINPUT8 / LPDIRECTINPUTDEVICE8 types and DI8 macros
- Replace custom MYDATA data format with c_dfDIMouse2 (8-button support)
- Use DIMOUSESTATE2 in GetDeviceState (correct size, 8 buttons)
- Add MOUSE5 button mapping via DIMOFS_BUTTON4
- Link against dinput8.lib; define required GUIDs inline to avoid dxguid.lib conflicts
- Fix .gitignore: remove Win32/ pattern that was shadowing code/win32/ source dir
