Stability fixes and the new Endurance upgrade

A campaign and progression stability update has been deployed.

• Endurance is now available with 100 levels. Each level gradually reduces suit-energy drain while sprinting; at level 100 you can sprint continuously for twice as long. Player speed is unchanged.
• The infinite XP farm on ep1_c17_05 and similar looping spawners is closed. The first 16 NPCs of the same class in one area reward normally; later spawns remain part of the campaign but grant no damage, kill, shared, or quest XP.
• The per-map XP cap now survives reconnects and emergency restarts, so reconnecting cannot reset it.
• Combat skills are disabled on ep2_outland_07, and the Advisor is protected from player, prop, and skill damage during Alyx's terminal scene.
• Unsafe third-party intervention in respawn points, vehicles, and map transitions has been removed. These systems are again owned by Synergy and the maintained SynFixes plugin.
• The home page is more compact, with news on the left and shared chat on the right. Live telemetry and client updates after deployments were also fixed.

We are continuing to monitor logs and crash dumps. If you find a repeatable issue, please send a website report with the map name and approximate time.
