- Add 5-minute stall detection for hung tool executions across all 4 session event handler paths. Auto-calls session.abort() and shows an error in the UI when a tool takes too long (e.g. backend drops connection mid-turn, which SDK 0.1.25 silently hangs on forever). - Upgrade @github/copilot-sdk from 0.1.25 to 0.1.29 which may include improved connection error handling.

Problem
When the Copilot backend drops the connection mid-turn (during tool execution), SDK 0.1.25 hangs silently forever — the session shows \ ool.execution_start\ but never \ ool.execution_complete. The UI is permanently stuck and the user has no way to recover without closing the tab.
Changes
Stall detection (\src/main/main.ts)
Added a 5-minute stall detector across all 4 session event handler paths:
This catches both truly hung commands and the backend-disconnect case.
SDK upgrade (\package.json)
Upgraded @github/copilot-sdk\ from \
