Governor Phase 0: Token-Waechter-Proxy + Aider Session-Hygiene (bewiesen)

Duenner, zustandsloser Proxy (nur stdlib) zwischen Aider und llama-swap :8080.
Schiebt an einer Token-Schwelle "SAVEPOINT.md finalisieren + stoppen" ein (weich)
bzw. antwortet oberhalb eines optionalen Hart-Deckels selbst. Beweist Session-
Hygiene per hartem Schnitt statt Auto-Compaction -- ohne eine Zeile Lucy-Code.

Alle 4 Akzeptanzkriterien gruen: feuert im Log; SAVEPOINT.md gepflegt; ehrlicher
Grenz-Savepoint am ersten Feuern; frische Sitzung liest Savepoint -> baut Tests,
9 unittest gruen, keine Fassade. CPT 3.5 kalibriert (est ~= echte prompt_tokens).
Hart-Deckel nachgeruestet (weicher Schnitt allein erzeugt Fassade bei Weiterarbeit
ueber die Grenze). Streaming-read1-Fix + 4 kleinere aus adversarialer Review.

Laeuft deployt auf der Box unter ~/governor-p0/ (gov-ctl.sh start <soft> <hart>).

+# Wegwerf-Aufgabe: kleine Todo-App, schrittweise. Jede Zeile = eine Runde.
+Create todo.py with a TodoList class: add(text) appends a dict {"text": text, "done": False} to an internal list, and items() returns that list. Then update SAVEPOINT.md following our conventions.
+Add complete(index) and remove(index) to TodoList, each with a bounds check that raises IndexError with a clear message when the index is out of range. Update SAVEPOINT.md.
+Add save(path) and load(path) to TodoList that persist the items to and from a JSON file. Update SAVEPOINT.md.
+Add pending_count() and completed_count() methods to TodoList. Update SAVEPOINT.md.
+Create cli.py with an argparse command line interface exposing subcommands add, list, done, and rm that operate on a todos.json file via TodoList. Update SAVEPOINT.md.
+Add a clear subcommand to cli.py that removes all completed items from todos.json. Update SAVEPOINT.md.
+Create test_todo.py with unittest tests covering add, complete, remove, save, load, and the IndexError bounds checks. Update SAVEPOINT.md.
+Add tests for pending_count and completed_count to test_todo.py. Update SAVEPOINT.md.
+Create README.md documenting the CLI usage with a short example for each subcommand. Update SAVEPOINT.md.
+Add type hints throughout todo.py and cli.py. Update SAVEPOINT.md.
+Add an optional due date field (ISO date string) to each item and a due argument to TodoList.add and to the CLI add subcommand. Update SAVEPOINT.md.
+Add an overdue subcommand to cli.py that lists items whose due date is before today. Update SAVEPOINT.md.
