/**
 * Waggle Behavioral Journey Tests
 *
 * End-to-end behavioral coverage for Waggle-specific intelligence systems.
 * Every test exercises the real implementation — no mocks, no stubs.
 *
 * Coverage:
 *   - Persona system: tool lists, system prompt composition, all personas
 *   - Trust model: risk classification journeys for capability installation
 *   - Confirmation gates: approval decisions across all tool categories
 *   - Injection scanner: multi-lingual, encoded, and authority-claim patterns
 *   - Loop guard: oscillation detection across rolling window
 *   - Command registry: all 13 slash commands execute with realistic context
 *   - Capability router: persona-aligned fallback chain resolution
 *
 * Why no server:
 *   These are behavioral unit tests for pure/near-pure modules.
 *   They run in <500ms, need no ports, and produce deterministic results.
 *   The HTTP pipeline is covered in chat-pipeline.test.ts.
 *
 * Run:  npx vitest run tests/behaviors/waggle-journeys.test.ts
