serge_shubin 7b942c77cf Server-side demo recording and playback (netdemo) — unified
Complete netdemo feature as a single commit on implant2:

Recording:
- svdemo_record/svdemo_stop commands
- Delta-compressed entity states and player states
- Server command capture (chat, prints)
- Configstring change tracking
- Keyframes at configurable interval for seeking
- Auto-record on map load (svdemo_autorecord)
- Auto-stop on map change, clean shutdown handling

Playback:
- svdemo_play loads map, spectator auto-connects
- Free camera with client-owned PmoveSingle (real-time, works paused)
- Player follow mode with full HUD
- Scoreboard with recorded player scores
- svdemo_pause with frozen trajectories and smooth unpause
- svdemo_seek (fast, keyframe-accurate) and svdemo_seekexact (precise)
- Seeking works from paused state
- SNAPFLAG_RESET_ENTITIES for clean map_restart and seek transitions
- Proper session/cvar/configstring handling across transitions
- svdemo_pauseEmpty waits for spectator before starting

Engine changes:
- usercmd_t: optional origin field for client-owned PVS
- msg.c: serialize optional usercmd origin
- cl_parse.c: SERVERCOUNT time delta reset for seek/unpause
- CG_SETCLIENTORIGIN trap for cgame-to-engine origin communication

cgame changes:
- Client-owned spectator camera (svDemoCameraPs)
- CS_SVDEMO configstring detection
- SNAPFLAG_RESET_ENTITIES entity interpolation reset
- Backwards time handling for seeking
- Local entity cleanup on seek
- Pause detection from frozen snapshot time
- Suppress connection interrupted during demo playback
