fix(copy): address PR #84 review — pacing, prerequisites, terminology

Review fixes for triangle activation monologue lines:

- CHANGELOG: correct smuggler line count (4 → 5), add D-035 ref
- Smuggler comment: align beat labels to 5-line structure
- Smuggler 040: "looking at" → "seeing" for body-first register
- Detective 043: rewrite to remove implicit manifest knowledge
  reference — line now works without fact prerequisite gate
- Detective 044: soften from near-certainty to enumerated
  possibilities with "insufficient data" qualifier
- Triangle comments: align to D-087 terminology (T1: Kael-
  Smuggler-Ring, T2: Sera-Detective-Commission)
- Schema description: note triangle_activated also missing from
  server Situation enum alongside greeting
- D-035 amendment: register triangle-signal, tell-observation
  tags and npc_in_los prerequisite as conventions

 - **Dissent:** None. Minor consolidations: Mellanie's 8 moods mapped to Gestalt's 8 (different names, same concepts). Mellanie's `crime` topic deliberately excluded (NPCs think of it as `cargo` or `money`).
 - **Amendment (Sprint 8):** `focused` added as 9th mood (used in Kael dialogue at The Terminal and maintenance corridors). `greeting` added as 14th situation (used in PC dialogue pools for initial contact lines). Schema updated to match.
 - **Amendment (Sprint 14):** Mood vocabulary renamed to match voice guide (monologue-voice-guide.md). Old → new: `fond`→`warm`, `comfortable`→`content`, `worried`→`anxious`, `concerned`→`frustrated`. Dropped: `analytical` (merged into `focused`), `conflicted` (modeled as `suspicious`+`warm` collision). Added: `hostile`. Final 8 moods: `anxious`, `frustrated`, `content`, `suspicious`, `warm`, `hostile`, `relieved`, `focused`. Neutral = untagged.
+- **Amendment (Sprint 24):** `triangle_activated` added as 15th situation (fires post-TriangleActivated when player observes anchor NPCs). Two freeform tags registered as conventions: `triangle-signal` (line is part of the triangle activation sequence) and `tell-observation` (line observes a behavioral tell without naming its cause). `npc_in_los` prerequisite added for LOS-gated monologue lines. Schema updated to match.
 - **Amendment (Sprint 15):** Line ID namespace changed from location-scoped to NPC-scoped. Old scheme: `{location_slug}_{d|m}_{###}` (e.g., `the-terminal_d_039`) — all NPCs at a location share one ID sequence, requiring cross-file coordination and causing collisions at scale. New scheme: `{npc-slug}_{d|m}_{###}` for dialogue, `{npc-slug}_m_{s|d}_{###}` for monologue (e.g., `kael-davan_d_001`, `dock-worker_d_001`). Each NPC's IDs are independent — no cross-file coordination needed. Auto-generated NPCs use their generated slug. Schema regex patterns unchanged (prefix is still `^[a-z][a-z0-9-]*`), only the `description` field and convention documentation update. Migration: mechanical rename of all existing line IDs across ~20 dialogue files and monologue pools.
