Make gameplay testing instructions more explicit — Claude Code
cannot launch CK3 or interact with the UI, so the test script
must clearly describe what the human player needs to do. Add
guidance on game speed and what to look for.

Create docs/TESTING.md with debug game rule, debug decisions per
milestone, log analysis commands, pre-launch validation script,
post-run analysis script, and Claude Code testing capabilities.
Add cross-reference to TESTING.md in each milestone's Testing
Checkpoints section (M1-M8).
