Fix cfg-dependent Clippy unused_mut failure in known log source construction

[Copilot]

Clippy was failing under -D warnings because build_known_log_sources() declared a mutable local that is only mutated on Windows. On non-Windows CI, the cfg-gated mutation is compiled out, leaving an unused_mut hard error.

• Root cause

  • build_known_log_sources() initialized sources as mutable and extended it inside a #[cfg(target_os = "windows")] block.
  • On Linux, that block does not compile in, so the binding is never mutated.

• Change

  • Reworked build_known_log_sources() to return platform-specific values directly:
    • windows_known_log_sources() on Windows
    • Vec::new() on non-Windows
  • This keeps behavior unchanged while removing the cfg-dependent lint.

• Result

  • Eliminates the unused_mut warning that was promoted to an error by Clippy in CI.

fn build_known_log_sources() -> Vec<KnownSourceMetadata> {
    #[cfg(target_os = "windows")]
    {
        return windows_known_log_sources();
    }

    Vec::new()
}

Pull request overview

Fixes a cfg-dependent Clippy warning in the Tauri backend by changing how known log sources are constructed, and updates GitHub Actions workflows to stop building macOS Intel artifacts.

Changes:

• Refactors build_known_log_sources() to avoid unused_mut when Windows-only code is cfg’d out.
• Removes macOS x86_64 (Intel) from the CI build matrix.
• Removes macOS x86_64 (Intel) from the release workflow matrix and release-notes downloads table.
