feat(copy): triangle activation proximity monologue lines (#597)
Author 4 smuggler and 5 detective monologue lines that fire when
the player observes triangle anchor NPCs post-TriangleActivated.
Smuggler (Kael Davan): physical observation → rationalization →
doubt → sensory confirmation. Contracted, personal, friend-arc.
Detective (Sera Venn/Torek): pattern recognition → deviation →
hypothesis → inference → procedural next step. Analytical,
institutional, evidence-cataloguing.
All lines: situation: [triangle_activated], trigger: observe_npc,
cooldown: 9999, priority: 8, prerequisite: npc_in_los: true.
Schema updated: triangle_activated added to situation enum,
npc_in_los added to prerequisites in monologue-pool.schema.json.
