`-m cron.scheduler` runs `cron/__init__.py` before the module itself. That
file's first import, `cron.jobs` -> `hermes_yaml` -> `ruamel`, is already a
third-party dependency. With the boot at the top of `cron/scheduler.py`, the
worker imported through the pinned PYTHONPATH alone:
- no lease on the generation was held yet;
- no `.pth` files had run;
- with the dependency pin removed, it still died with
"No module named 'ruamel'".
Run the marked-worker boot at the top of `cron/__init__.py`, under a private
alias, so the package attribute `cron.worker_bootstrap` stays the module. Drop
the now-redundant call in `scheduler.py`. Replace the in-process marker test
with a subprocess test: the boot runs before `cron.jobs` is imported, runs
exactly once, consumes the marker, and never fires for an unmarked importer.
Also add the missing trailing newlines on the two new files.
