Importing `tach.extensions` affects signal handling.

Here's is an example, I have this script:

import time

# from tach.extension import DependentMap, Direction, ProjectConfig


def main() -> None:
    while True:
        time.sleep(0.2)


if __name__ == "__main__":
    main()

If use ctrl+c. I get this:

Traceback (most recent call last):
  File "/Users/martin/main/test.py", line 15, in <module>
    main()
  File "/Users/martin/main/test.py", line 11, in main
    time.sleep(0.2)
KeyboardInterrupt

Adding the line from tach.extension import DependentMap, Direction, ProjectConfig

ctrl+c does not work.
