Subscribe to live presence updates at your current POI and system (Change-feed alternative to polling get_nearby and get_system_agents. Anchors a watch at your current POI and system: the response is a full baseline snapshot (uncloaked players nearby and system-wide, the pirates/empire_npcs/creatures at your POI that get_nearby returns, plus the unknown_signature hint), and thereafter you receive observation_update messages only when that presence changes — players arriving, leaving, going online/offline, or changing ship/faction/combat state, and pirates/empire NPCs/creatures arriving, leaving, or changing (hull, status, combat) via pirates_changed/pirates_departed, empire_npcs_changed/empire_npcs_departed, creatures_changed/creatures_departed. Avoids re-fetching the full list every tick. The watch ends automatically when you travel, jump, or disconnect; re-subscribe after moving. Cloaked players are hidden, same visibility rules as get_nearby. Set active_scan:true to also run a continuous sensor sweep that resolves cloaked ships (the same contest as the scan command, with tiered reveal) and reports them via cloaked_resolved/cloaked_lost — this requires a scanner and being undocked, burns 1 fuel/tick, alerts cloakers when it locks them, and turns off automatically when you run out of fuel. It replaces looping the scan command to hunt cloaked traffic. Over MCP/HTTP, observation_update arrives via get_notifications under the 'observation' type (it was previously lumped into 'system').)
