test(simulation): Sprint 24 tests — archetype, tell escalation, ticker, v0.1 playthrough (#593, #595)

- 7 archetype→monologue regression tests (smuggler/detective pool partitioning)
- 3 tell escalation unit tests (RoutineDeviation insertion + expiry)
- 6 news ticker tests (pool loading, SimRng rotation, zone gating)
- 3 live integration tests against real server binary (Layer 3)
- Update existing tests for current_ticker field and protocol v19

+//! Regression tests: character archetype flows end-to-end to MonologueState (#595, D-032).
+//!
+//! Verifies that when a session starts with a given CharacterArchetype, the
+//! player entity's MonologueState.character reflects it correctly. This is the
+//! guard against the default "detective" string leaking into smuggler sessions.
+//!
+//! Two complementary approaches:
+//! 1. Unit-level: CharacterArchetype::as_monologue_key() mapping is correct.
+//! 2. Integration (gauntlet): setup_gauntlet() correctly wires archetype → MonologueState.
+//!
+//! Spec refs:
+//!   D-032: character tag is a hard pool partition, not a filter — wrong character string
+//!          silently serves wrong content.
+//!   D-010: no player identity baked into game loop — archetype is a configuration.
+//!   #587:  character_archetype added to StartupMessage; monologue key derived from it.
+//!   #595:  MonologueState.character initialized from CharacterArchetype at session start.

+//! Integration tests for tell escalation on triangle activation (#589, D-024 axis 9).
+//!
+//! Covers:
+//! - D-027 criterion 4: RoutineDeviation tell must be observable after activation
+//! - D-024 axis 9: tell system is a simulation output, not authored content
+//! - #589: escalate_tells_on_activation system inserts RoutineDeviation on triangle NPCs
+//!
+//! Test structure:
+//! - Layer 1 (pure): verify RoutineDeviation dominates all other tells (already
+//!   covered by unit tests in tell_state.rs, regression guards here)
+//! - Layer 2 (ECS world): verify activation event → RoutineDeviation insertion (pending #589)
+//! - Layer 2 (ECS world): verify expired RoutineDeviation is removed (pending #589)
+//!
+//! Pending tests are marked #[ignore] — they compile against the current API but
+//! will fail until escalate_tells_on_activation is registered in StorytellerPlugin.
