Stream Lark/Feishu events as NDJSON with bounded runs and subprocess-safe exit contracts.

• Consume real-time events (IM messages, reactions, chat changes, VC meetings, Minutes) via lark-cli event consume <EventKey>, with optional jq filtering and --max-events / --timeout bounds
• Emits a stderr ready marker before stdout, supports stdin EOF for graceful shutdown, and reports exit reason (limit/timeout/signal/error) for reliable orchestration
• One EventKey per process; use lark-cli event list and lark-cli event schema to discover keys and inspect output schemas before consuming
• Requires lark-cli binary and Lark authentication configured via lark-shared skill; avoid kill -9 on processes with PreConsume hooks to prevent server-side subscription leaks
