Add src-tauri/.cargo/config.toml with --exclude-all-symbols linker flag
for x86_64-pc-windows-gnu. MinGW auto-exports ~106k public Rust symbols
into the cdylib export table, exceeding the 65,535 PE ordinal limit.
The desktop binary links against rlib (static) so the cdylib export table
is unused. An empty export table is a valid DLL.
