7619407b63
Adds `src/self_tdd/watchdog.py` with a `_run_tests()` function that
shells out to pytest and a `watch` command that polls on a configurable
interval, printing green on recovery and full short-traceback output on
regression. No files are modified and no commits are made automatically.
Usage:
self-tdd watch # default 60s interval
self-tdd watch -i 15 # poll every 15s
Also adds 6 unit tests and wires the `self-tdd` entry point +
`src/self_tdd` wheel include into pyproject.toml.
