Ricardo 0fe99ee5b1 perf: add timeout and watch-mode cache extension to all data files ...

Introduce shared cachedFetch helper (lib/data-fetch.js) wrapping
EleventyFetch with two protections:

- 10-second hard timeout via AbortController on every network request,
  preventing slow or unresponsive APIs from hanging the build
- 4-hour cache TTL in watch/serve mode (vs 5-15 min originals), so
  incremental rebuilds serve from disk cache instead of re-fetching
  APIs every time a markdown file changes

All 13 network _data files updated to use cachedFetch. Production
builds keep original short TTLs for fresh data.

Targets the "Data File" benchmark (12,169ms / 32% of incremental
rebuild) — the largest remaining bottleneck after filter memoization.
