v0.1.18

• fix: 5dive doctor --json crashed with STOP_FAILURE_HOOK: unbound variable (stale checks for hook paths that moved into the telegram plugin). Removed the obsolete checks.
• fix: grok telegram agents went dead on the nightly unit restart — grok lazy-loads its telegram MCP server only once a chat session starts, so it sat at the launcher receiving nothing. 5dive-agent-start now nudges grok into a session at boot (mirrors the codex trust-accepter), after which the telegram-grok server's watchdog owns the loop.
