Krzysztof kuhy Rudnicki 6a9f137845 fix: HLTB matching uses game_alias for renamed games & hide library on reassign
- _pick_best_hltb_entry: check game_alias in exact-match fallback so
  renamed games (e.g. 'Needy Streamer Overload' -> 'NEEDY GIRL OVERDOSE')
  are not beaten by spinoffs with matching prefixes
- _try_reassign_shorter_game: call hide_other_games after pick_next_game
  so library visibility is updated on reassignment, not only on completion
- Added tests for alias matching and all hiding branches (100% coverage)

"""HowLongToBeat integration for estimating game completion times.
Fetches leisure completionist hour estimates from howlongtobeat.com with:
- direct API calls (bypassing the slow howlongtobeatpy per-request setup)
- single shared aiohttp session for all requests
- concurrent requests with configurable concurrency
- live progress reporting via callback
- incremental disk-cache saves so crashes don't lose work
- leisure time (upper-bound play time) from individual game pages
- DLC time aggregation (base game + all DLC leisure times combined)
