Four bugs fixed:
- HLTB search returned 0 results for ~87 games with special chars (™, ®, &,
standalone -, (Legacy), RHCP, etc.) — add _sanitize_search_name() and
extend _build_search_variants() with Steam-suffix and edition stripping
- fetch_hltb_detail_missing returned immediately because `app_id not in rush`
was always False (all keys present with -1) — fix to `rush.get(id,-1) <= 0`
- save_hltb_cache overwrote rush/leisure on confidence-only partial saves —
now reads existing cache and preserves data when extras dicts are empty
- _filter_qualifying_games excluded 57 games with stale snapshot hours (-1)
even though HLTB hours cache had valid data — add cache fallback
Result: stats shows Rush 64,670h / Leisure 136,807h / Worst 228,594h for
all 785 qualifying games with full rush+leisure detail.
