Refactor Ghidra instructions, add new binary files, and enhance decompilation notes

Browse source 
- Updated Ghidra instructions to emphasize keeping analysis batches small.
- Added new binary files: `db.104.gbf`, `db.105.gbf`, and `db.27.gbf`.
- Expanded decompilation notes for `cheat_code_check`, detailing its internal workings and verified cheat actions.
- Revised segment coverage ledger to reflect new findings and promote segments from `Foothold` to `Partial`.
- Enhanced `plan-mid.md` with updated estimates and focus areas for ongoing analysis.
