v1.1.82 - Fix MCP idle timeout with deferred connection

Fix: MCP Idle Timeout (v1.1.82)

Problem: Atlassian MCP server has a ~45-50 second idle timeout. Connection was made too early and died before use.

Solution: Defer MCP connection until right before notification dispatch (after AI spec generation).

Changes

• Moved MCP connection to right before ticket creation
• Enhanced isConnected() to validate process is alive
• Reduced idle window from 2+ minutes to < 10 seconds

Deployment: Update DemoMDP workflow to v1.1.82
