Handle Electron sleep/resume renderer recovery

[turesheim]

Summary

• add Electron main-process sleep/resume handling for renderer OOM, crash, kill, and unresponsive states
• add a frontend resume contribution that reloads when Theia's backend connection remains unhealthy after wake
• guard Electron window-event sends so disposed or crashed frames are skipped

Verification

• npm run build --workspace @commodore-commander/theia-extension
• npm run theia:build
• npm test --workspace @commodore-commander/theia-extension

Remaining manual work

• Verify the real macOS sleep/wake scenario with the same emulator/SIDScore workload that triggered the OOM.

Assumptions

• Reloading a crashed or unresponsive renderer after wake is preferable to leaving the IDE wedged.
