cleanup: remove AI slop docs and move scripts to dev/

Remove V2_CONTEXT.md, PLAN_V2_MONOLITHIC.md, and
PR_ADVERSARIAL_REVIEW.md — session artifacts that don't belong in the
repo.

Move audit_direct_access_clang.py and strip_non_universal.py from
scripts/ to dev/ since they are build/CI tooling, not game scripts.
Update .github/workflows/build-pr.yml and dev-release.yml to the new
path. Remove stale __pycache__/.
