Fixed
- Steam Proton installs are now auto-detected.
The detector previously only checkedsteamapps/common/, which is the native
Steam path. Proton/Steam Play installs live under
steamapps/compatdata/<appid>/pfx/drive_c/, a completely different tree.
The detector now scans all compatdata prefixes under both
~/.local/share/Steamand~/.steam/steam(handles the symlink case),
so WoW installed via Proton is found automatically without requiring a manual
path in Settings. - Log message now correctly identifies a missing AppHelper addon.
"No valid WoW game-version directory found" was logged whenever the
TradeSkillMaster AppHelper addon folder was absent, even though the WoW
directory itself was correctly detected. The message now reads
"TradeSkillMaster AppHelper not found in any WoW install" to make the
actual cause clear.
