Build on @aydnOktay's cronjob fix by routing the cronjob check through
the shared 'env_var_enabled' helper in utils.py (same truthy set:
1/true/yes/on) and applying the same semantics to the 8 sibling call
sites that read HERMES_INTERACTIVE / HERMES_GATEWAY_SESSION /
HERMES_EXEC_ASK / HERMES_CRON_SESSION with bare os.getenv() truthy
checks:
- tools/approval.py: _is_gateway_approval_context (2), check_command_safety (2),
check_all_command_guards (3) -- 7 sites total
- tools/terminal_tool.py: _handle_sudo_failure, sudo password prompt -- 2 sites
- tools/skills_tool.py: _is_gateway_surface -- 1 site
Without this, a user who exports HERMES_INTERACTIVE=0 in their shell
still gets interactive sudo prompts, approval prompts, and gateway
skill-install paths -- only the cronjob tool was hardened. Now all
consumers agree on the same false-like values.
Also drops the duplicate _is_truthy_env helper from cronjob_tools.py
in favour of the existing canonical utils.env_var_enabled.
Tests: extend the parametrized regression coverage to all three
session env vars (HERMES_INTERACTIVE / HERMES_GATEWAY_SESSION /
HERMES_EXEC_ASK) symmetrically. tests/tools/test_cronjob_tools.py:
60/60 pass; tests/tools/{approval,terminal_tool,skills_tool,
cron_approval_mode,hardline_blocklist}.py: 378/378 pass.
