Multi-dir plugin loading, VFS Root Builder, Wine registry check, column visibility fix

Plugin loading:
- Remove symlink-based ensureBundledPluginsLinked(), replace with multi-dir
  search (bundled dir takes priority, instance dir adds extras only)
- Auto-clean stale symlinks from instance plugins/ dirs on startup
- Add mergedProxyList() for proxy plugin discovery across both dirs

VFS Root Builder (replaces Python rootbuilder.py):
- Native C++ Root Builder integrated into FuseConnector
- Deploy mod Root/ files to game dir before FUSE mount, clear on unmount
- Per-instance toggle in Instance Manager (default: on)
- Root Builder path normalization in processrunner.cpp: rewrite binary and
  start-in paths from mods/.../Root/ to Game Root for correct Wine path
  resolution (fixes SKSE + EngineFixes versionlib lookup)
- Expose game dir and prefix to SLR pressure-vessel via --filesystem=

Wine registry check:
- Read/write Wine prefix system.reg (HKLM) with timestamp-aware parsing
- Auto-check game install path before launch, prompt to fix if mismatched
- Updates both Software\ and Wow6432Node\ registry keys

Column visibility fix:
- Guard updateGroupByProxy() during QHeaderView::restoreState() to prevent
  sort indicator restoration from triggering setSourceModel() which resets
  all columns to visible

Python proxy:
- Skip FixGameRegKey.py, crashlogtools, rootbuilder.py (Windows-only or
  replaced by native implementations)
