feat(scraper): add on_error callback to scrape_contest_metadata

Browse source 
Problem: `scrape_contest_metadata` silently swallowed failures — the
callback simply never fired, giving callers no way to detect or react
to scraper errors.

Solution: Add optional `on_error` parameter invoked on scraper failure
or empty problems result. Backward-compatible — existing callers are
unchanged.
