Subject: [PATCH] chore(build): bind Windows cargo-test binaries to
 Common-Controls v6 manifest (#1257)

On Windows/MSVC the test executables for `psysonic-analysis`, `psysonic-audio`
and the top `psysonic` crate link the wry/tao windowing runtime (via the tauri
dependency) and statically import `TaskDialogIndirect` from comctl32. That symbol
only exists in Common-Controls v6; System32 comctl32.dll is v5.82 and lacks it,
so an unmanifested test exe aborts at startup with STATUS_ENTRYPOINT_NOT_FOUND
(0xC0000139) before any test runs. The app binary avoids this through the
manifest tauri_build embeds.

Declare the Common-Controls v6 dependency on the test binaries via build-script
link args, gated to windows-msvc. The app binary's manifest is unchanged
(byte-identical: tauri_build already embeds the same dependency, the linker
dedupes). Non-Windows/CI builds are unaffected.
