docs(testing): record live original comparison

Document the Wine-backed original start and charged-launch captures, the matching deterministic Rust states, and the remaining boundary that a chosen claw terminal was not forced in the live original.

Test Plan:
- Launch original/TDKPIN.EXE with Wine 11.15 staging
- Send keypad plus, hold Down for 1.1 seconds, release, and inspect captures
- Compare original started state with Rust launcher step zero
- git diff --cached --check
