agent_vscode d4d05c8e8b test(ai-chat): add dev-only perf harness for the chat stream pipeline
Mounts the real ChatThread against a synthetic AI SDK v6 UI-message SSE
stream (multi-step reasoning + getPage tool calls + markdown answer;
5k/20k/50k-token presets, 15/5 ms chunk cadence) with long-task, FPS
and mount-time instrumentation. Two scenarios: mount a persisted
transcript (open-chat cost) and stream a live turn through the real
useChat pipeline via a window.fetch patch scoped to /api/ai-chat/stream.

Served only by the vite dev server at /perf/ai-chat-perf.html; the
production build keeps its single index.html entry, so none of this
ships. Also ignore local trace dumps under .claude/perf-traces/.
