Multiple issues fixed for seamless transitions:
Server lifecycle:
- SV_Shutdown before devmap in SVD_Play_f: drops old clients so
spectator doesn't land in slot 0 (recorded player collision)
- SVD_IsStarting flag prevents cleanup hooks from destroying demo
state during our own SV_Shutdown/SV_SpawnServer calls
- SV_SpawnServer stops demo playback on non-demo map changes
via SVD_CleanupPlayback (no disconnect, just state cleanup)
- SVD_CleanupPlayback made non-static for use from sv_init.c
Cvar handling:
- Use Cvar_Set2 with force=qtrue for CVAR_ROM sv_demoplaying
- Set cvar AFTER SV_Shutdown (old game module gone) but BEFORE
devmap (so new G_InitGame reads correct value)
- Set CS_SVDEMO configstring after devmap as backup for cgame
Game module:
- ClientBegin: set pm_type=PM_SPECTATOR after ClientSpawn (which
memsets ps). ClientThink_real normally sets this but is disabled
in demo mode.
- G_WriteSessionData: skip during demo playback so forced
TEAM_SPECTATOR doesn't persist to next normal game
- ClientThink: return early in demo mode (no server-side movement)
Removed debug prints and unused SVD_GetPlayMaxClients.

- Set sv_demoplaying before devmap so game module knows during
ClientConnect/ClientBegin
- Call ClientUserinfoChanged after forcing spectator team so
CS_PLAYERS configstring has correct team value for cgame
- Record sanitized playerState for spectators (pm_type=PM_SPECTATOR,
PERS_TEAM=TEAM_SPECTATOR) so they show correctly on scoreboard
instead of appearing as regular players from follow-mode corruption

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)
