Fix: Use dynamic bin path resolution for SPM binaries

The formula was using hardcoded .build/release/ paths which don't
resolve correctly in Homebrew's build sandbox. SPM places binaries
in triple-specific directories (e.g. .build/arm64-apple-macosx/release/)
and the symlink doesn't always work with Ruby's file operations.

Now using 'swift build --show-bin-path' to dynamically resolve the
correct binary location.
