Bare `float(os.getenv("HERMES_CRON_TIMEOUT", 600))` in `run_job()` raises
a `ValueError` when the env var is set to a non-numeric string (e.g. "abc").
Replace it with the same defensive try/except pattern already used by
`_get_script_timeout()` for `HERMES_CRON_SCRIPT_TIMEOUT`: log a warning
and fall back to the 600 s default instead of crashing.
Also update the existing env-var tests to exercise the new code path and
add two new tests — one for an invalid value, one for an empty string.
Fixes#11319

Port the gateway's inactivity-based timeout pattern (PR #5389) to the
cron scheduler. The agent can now run for hours if it's actively calling
tools or receiving stream tokens — only genuine inactivity (no activity
for HERMES_CRON_TIMEOUT seconds, default 600s) triggers a timeout.
This fixes the Sunday PR scouts (openclaw, nanoclaw, ironclaw) which
all hit the hard 600s wall-clock limit while actively working.
Changes:
- Replace flat future.result(timeout=N) with a polling loop that checks
agent.get_activity_summary() every 5s (same pattern as gateway)
- Timeout error now includes diagnostic info: last activity description,
idle duration, current tool, iteration count
- HERMES_CRON_TIMEOUT=0 means unlimited (no timeout)
- Move sys.path.insert before repo-level imports to fix
ModuleNotFoundError for hermes_time on stale gateway processes
- Add time import needed by the polling loop
- Add 9 tests covering active/idle/unlimited/env-var/diagnostic scenarios
