docs(viz): agent_runs_timeline.md — frontmatter + self-doc
Issue 0118. Frontmatter completo (kind, lang, domain, version, purity,
signature, params, tags=agents/timeline/sse/imgui/viz/panel,
uses_functions=http_request_cpp_core, error_type, tested).
Secciones obligatorias por contrato self-doc:
- ## Ejemplo — wiring concreto con TimelineState g_state + lock + render
- ## Cuando usarla — dashboard cross-app de agentes
- ## Gotchas — SSE stub, ts en segundos, mutex obligatorio, no autoscroll,
ImGuiSelectableFlags_AllowOverlap (rename desde AllowItemOverlap),
app chip hex hardcoded, since_ts no determinista en tests
