refactor: move research scripts out of minicode/ + add mypy + property-based tests

- Move 6 paper/eval scripts (paper_a_*, cybernetic_ablation, runtime_profile_eval)
  + their tests to minicode-research/ — product package is now 78 modules (was 84)
- Add mypy config (pyproject.toml [tool.mypy]) — 241 errors baseline (mostly
  agent_loop + timeline_memory, untyped function bodies)
- Add tests/test_property_based.py: hypothesis fuzz tests proving parse_input_chunk
  and transcript layout never crash on arbitrary byte/CJK/control input (500+200 cases)
- Fix: adaptive_pid_tuner callable→Callable typo, input_parser name_map redefinition
