Merge PR #538: fix cron HERMES_HOME path mismatch, missing HomeAssistant toolset mapping, Daytona timeout drift

Authored by Himess. Three independent fixes:
- cron/jobs.py: respect HERMES_HOME env var (consistent with scheduler.py)
- gateway/run.py: add Platform.HOMEASSISTANT to toolset mappings
- tools/environments/daytona.py: use time.monotonic() for timeout deadline

gateway/run.py
