FUSE VFS performance: attr cache, selective invalidation, init tuning

2026-03-08T06:45:11Z

- Increase ATTR_CACHE_SECONDS from 1.0s to 30.0s (90% getattr reduction) - Replace nuclear clearDirCache() with selective invalidateDirCache() that only clears the affected parent directory instead of all caches - Add mo2_init callback: enable FUSE_CAP_AUTO_INVAL_DATA for kernel page cache retention across open/close, increase max_readahead/max_write to 1MB - Switch open_files_mutex to shared_mutex for concurrent read access - Add perf handoff doc for VFS optimization history Co-Authored-By: Claude Opus 4.6

Remove umu-run, keep game as child process for Steam tracking

2026-02-23T23:44:12Z

- Remove umu-run entirely (crashed due to pressure-vessel/FUSE incompatibility) — use raw `proton run` instead - Replace startDetached() with QProcess::start() so the game stays in Fluorine's process tree. This lets Steam track the game lifetime and makes the "close game" button work when Fluorine is added as a non-Steam game. - Add writeIniValueDirect/readIniValueDirect for safe Bethesda INI handling without QSettings corruption - Fix prefix_setup.rs to skip umu-run bootstrapping - Clean up settings UI, build scripts, and docs for umu-run removal Co-Authored-By: Claude Opus 4.6
