feat(scraper): add checkpointing and richer page extraction

Add resumable checkpoint support so long scrapes can recover from
interruptions instead of restarting from scratch.

- introduce autosave/load/clear checkpoint flow in `.cache/scrape-state.json`, including SIGINT/SIGTERM save-on-exit handling
- expand parsing/model output to capture legacy and portable infobox fields, primary image URLs, effects, recipes, raw tables, and improved category extraction
- skip infobox tables during recipe parsing to avoid false recipe matches
- add cache log event type, ignore cache/output artifacts, and document new autosave tuning options in READMEfeat(scraper): add checkpointing and richer page extraction
