fix: exclusion reasons from YAML, not hardcoded in Python

Added exclusion_note field to emulator profiles. verify.py reads
this field instead of parsing notes text with fragile keywords.

desmume2015: explains .info vs code discrepancy
dolphin_launcher: explains standalone BIOS management

All exclusion messages now come from YAML data, not Python strings.

 notes: |
   Frozen 2015 snapshot of DeSmuME. The external BIOS loading feature
   (desmume_use_external_bios) does NOT exist in this version.
-  The .info declares firmware_count=3 but the code never loads them.
   Verified: libretro.cpp has no bios7/bios9/firmware path construction.
