+/**
+ * Chat Pipeline Behavior Tests
+ *
+ * Tests the `/api/chat` SSE pipeline and its helper functions.
+ * Split into two layers:
+ *   1. Pure function unit tests — `applyContextWindow`, `buildSkillPromptSection`
+ *      (no server, instant, deterministic)
+ *   2. HTTP integration tests — injection blocking, SSE event sequence,
+ *      session history, agentRunner injection seam
+ *      (starts `buildLocalServer` on port 0, uses fetch())
+ *
+ * Why these gaps matter:
+ *   - `applyContextWindow` is responsible for the 50-message sliding window + context
+ *     summary. A regression here silently drops user context.
+ *   - `buildSkillPromptSection` controls how skills reach the LLM system prompt.
+ *   - The HTTP injection blocker is a security gate — it must return 400 before
+ *     the agent loop runs.
+ *   - The agentRunner seam is the testability contract for all behavioral tests.
+ *     If it breaks, the rest of the pipeline is untestable without a real LLM.
+ *
+ * Run:  npx vitest run tests/behaviors/chat-pipeline.test.ts

+ *   - 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.
