v0.6.80

Исправления

• a timed-out discuss abandons its ask; ended-subagent replies are a pointer
• a discuss wait across an app restart stays queued
• a second start without a command finds the running app and exits
• AGENTLINK_JSON_UTF8=1 prints raw UTF-8 JSON
• a reopened ask waits 2 minutes for a live session before a launch
