* fix(tools): remove unnecessary crontab requirement from cronjob tool
The hermes cron system is internal — it uses a JSON-based scheduler
ticked by the gateway (cron/scheduler.py), not system crontab.
The check for shutil.which('crontab') was preventing the cronjob tool
from being available in environments without crontab installed (e.g.
minimal Ubuntu containers).
Changes:
- Remove shutil.which('crontab') check from check_cronjob_requirements()
- Remove unused shutil import
- Update docstring to clarify internal scheduler is used
- Update tests to reflect new behavior and add coverage for all
session modes (interactive, gateway, exec_ask)
Fixes#1589
* test: add HERMES_EXEC_ASK coverage for cronjob requirements
Adds missing test for the exec_ask session mode, complementing
the cherry-picked fix from PR #1633.
