Remove NaK/Rust dependency, port remaining functionality to native C++

Replace NaK Rust crate and nak_ffi with native C++ implementations:
- Game detection (Steam, Heroic, Bottles), VDF parser, icon extraction
- Prefix symlinks, SLR manager, Steam path detection
- Known games database

Add FUSE VFS optimizations: zero-copy reads via fuse_reply_data,
default_permissions mount option, FUSE_CAP_ASYNC_DIO, FUSE_CAP_EXPIRE_ONLY,
lookup cache parent index, cached mode bits, increased I/O buffer sizes.

Update build system, prefix setup, and various fixes.
