0.1.14

Fixed macOS setup failing on newer systems (#3) — StemKit no longer picks up system Python versions newer than 3.12 (which the pinned audio engine doesn't support), falling back to its bundled Python instead. Setup now also rebuilds a broken environment from a previous failed attempt, so no manual cleanup is needed.

Thanks to @cpiprint for the fix (#4) and @joecer21 for diagnosing the root cause and the venv rebuild suggestion.
