add probe subcommand for end-to-end relay health checks

Implements grasp-audit probe with full write path (publish events,
poll for repo init, push, verify refs match state) and read-only
fallback (find existing announcement, fetch refs). Supports --nsec
for whitelisted relays, --json output, and --watch for continuous
monitoring.
