* feat(ghidra): admit explicit DOS COM analysis

identity, seed real-mode entry/context before Ghidra analysis, and verify
complete loaded bytes, source mappings and measured register context.
Keep original binaries unchanged and PSP/runtime coverage explicit.

* fix(verification): validate COM package selection before allocating fixtures
