chore: add retoor header to all devplacepy source files and update style agent header rule

The diff adds the mandatory `retoor <retoor@molodetz.nl>` header comment to every `.py` file under `devplacepy/` (including `__init__.py` and `routers/__init__.py`), and updates the `StyleAgent` in `agents/style.py` to instruct agents to only add the header on created or already-edited files rather than sweeping the entire repo. The `agents/base.py` operating protocol is also revised to reorder and clarify tool discipline rules.
