Subject: [PATCH] fix: report 429 retry + theme toggle on all pages
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- LLMClient: increase retries 5→8, backoff 1s→2s, max 30s→60s for GLM rate limit recovery
- Report agent: add 3s delay between sections to avoid sustained 429
- Add theme-toggle-anchor to SimulationRun/Report/Interaction/Replay views
- All pages now have dark/light theme toggle button
