chore: release v0.5.7

[github-actions]

🤖 New release

• wadtools: 0.5.6 -> 0.5.7

Changelog

0.5.7 - 2026-07-13

Added

• add paths command
• add project icon
• implement mimir hashtables
• windows explorer integration
• bin scan extract

Changed

• Hash → path resolution now uses the mimir shared
  .lhdb cache instead of CommunityDragon hashes.*.txt files. Tables are memory-mapped and
  shared across LeagueToolkit tools, so there is no per-run parse of a ~250 MB text blob.
• download-hashes / dl now installs the published mimir tables into the shared cache
  (checksum-verified, atomic, incremental) instead of downloading CommunityDragon text files.
• hashtable-dir / hd now prints the mimir cache directory; --hashtable-dir and the
  hashtable_dir config value now override that cache directory (also settable via MIMIR_DIR).
• -H/--hashtable <PATH> still loads a supplemental <hex-hash> <path> text file, layered on
  top of the cache.

Removed

• On first run after upgrading, the old Documents/LeagueToolkit/wad_hashtables
hashes.game.txt / hashes.lcu.txt files are removed (best-effort; custom files are left
  untouched and the folder is deleted only if it becomes empty).
