M20SIX v2.0 — ORGAnelle M COMPATIBILITY TEST 1

Purpose
-------
This is the same M20SIX v2.0 Advanced Drums patch engine with a compatibility
launcher for Organelle M/S/S2 systems that use different SuperCollider paths
or audio-server setups.

Changes in this test build
--------------------------
1. Searches explicitly for sclang in PATH, /usr/bin and /usr/local/bin.
2. Forces Qt to offscreen/headless mode for older SuperCollider builds.
3. Uses supernova when available, otherwise falls back to scsynth.
4. Searches several known Organelle locations for start-jack.sh.
5. If the firmware JACK helper is absent but jackd exists, tries the classic
   Organelle JACK command as a fallback.
6. Writes startup diagnostics to:
   /sdcard/data/m20six/m20six-log.txt

Install this as a separate patch. Do not replace the stable release while it
is being tested.

If it still fails, report the Organelle model + OS version and send the log
file above.
