v0.2.1

PrefixPug v0.2.1

A safe Steam/Proton compatdata and shader cache cleaner written in Rust.

Highlights in this Release

• Steam Deck & Decky Loader Plugin: Added native SteamOS Decky Loader plugin for one-tap Game Mode Quick Access Menu (QAM) scanning, save vaulting, and shader cache cleanup.
• Steam Cloud Sync Intelligence: Inspects account remotecache.vdf and remote/ directories to flag whether local saves have cloud backups (SteamCloudStatus::Synced vs NotDetected).
• Staleness Audit: New --stale flag on prefixpug audit to filter installed games with prefixes untouched for >90 days.
• Steam Deck Storage Expansion: Added fallback discovery paths for Steam Deck microSD storage (/run/media/mmcblk0p1/) and Flatpak paths.
• Anti-Cheat Runtime Protection: Explicitly deny-listed EasyAntiCheat (1826330) and BattlEye (1161040) runtimes from deletion.
• Updated Manpage: Added documentation for backups, restore, completions, and --stale in man prefixpug.

• Blocklist Save Engine: Inverted whole-root save archiving with SHA-256 fsync verification before prefix removal.
• Standalone Save Vaulting: prefixpug vault <APPID>, prefixpug backups, prefixpug verify-backup, and prefixpug restore.
• Honest Disk Sizing: Measures allocated filesystem blocks (st_blocks * 512) and free space delta via statvfs.
