fix(cron): SSH dispatch validation + failure detection + broken import

1. New cron/ssh_dispatch.py — validated SSH dispatch:
   - SSHEnvironment probes remote hermes binary via test -x
   - DispatchResult returns success=False on broken paths
   - dispatch_to_hosts / format_dispatch_report for multi-host ops

2. cron/scheduler.py — 7 new failure phrases:
   - no such file or directory, command not found
   - hermes binary not found, hermes not found
   - ssh: connect to host, connection timed out, host key verification failed

3. cron/__init__.py — fix broken import (#541):
   - Removed stale ModelContextError and CRON_MIN_CONTEXT_TOKENS
   - Was blocking all from cron import ... calls

Closes #561 (Closes #350, #541)
