CMM: gocmm-debug probes the startup NRE (part-group match), checks real exe

Browse Source 
goCMM matches the registry 'Selected Part Group' against the
ApplicationSettings.xml <PartGroup FullName> entries with a case-sensitive
compare. No match -> SelectedPartGroup null -> "Object reference not set to
an instance of an object" at start. This is a different failure from the
registry SecurityException the script already probes.

- PROBE 3: read the reg value (32-bit view) + every FullName in the XML,
  Ordinal-compare, and report exact / case-only / no-match / missing-XML.
  Case-only and no-match name the d441abd canonicalization fix as the remedy.
- Version check now looks for the real goCMM.exe, not the nonexistent
  GEAOperatorFriendlyInterface.exe (was a false MISSING).
- .bat header documents both failure modes it now diagnoses.
