fix: web_extract fast-fail on scrape timeout + summarizer resilience

- Firecrawl scrape: 60s timeout via asyncio.wait_for + to_thread
  (previously could hang indefinitely)
- Summarizer retries: 6 → 2 (one retry), reads timeout from
  auxiliary.web_extract.timeout config (default 360s / 6min)
- Summarizer failure: falls back to truncated raw content (~5000 chars)
  instead of useless error message, with guidance about config/model
- Config default: auxiliary.web_extract.timeout bumped 30 → 360s
  for local model compatibility

Addresses Discord reports of agent hanging during web_extract.
