The `bottles` dict held `@contextmanager`-wrapped launch contexts. On normal Python interpreter shutdown those context managers' generators got GC'd, which raised GeneratorExit at the yield point and ran the `finally` block — invoking each bottle's teardown and tearing down the compose project. Net effect: `q` WAS implicitly stopping every dashboard-launched bottle even though the keypress handler just `return`'d. `os._exit(0)` skips all Python-level cleanup (GC, atexit, etc.), so the docker compose projects survive the dashboard exit untouched. Curses gets explicit `endwin()` first because the brutal exit skips curses.wrapper's normal terminal restoration. Matches PRD 0020's resolved-question answer (`q` does NOT tear down bottles; teardown is always explicit via `x` or `./cli.py cleanup`).
