fix(cron): SSH dispatch validation, failure detection, broken import (#350, #541)

Three fixes:

1. New cron/ssh_dispatch.py — validated SSH dispatch
   SSHEnvironment probes remote hermes binary via test -x before dispatch.
   DispatchResult returns success=False on broken paths, not silent OK.
   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.
   Detected by _detect_script_failure() so broken dispatches are flagged.

3. cron/__init__.py — fix broken import (#541)
   Removed stale ModelContextError and CRON_MIN_CONTEXT_TOKENS imports
   that dont exist in scheduler.py. Blocked all 'from cron import' calls.

Closes #350, Closes #541
