🤖 fix: resolve flaky integration tests in bash runtime and stream resumption

Generated with mux

Fixes two independent flakes:
1. tests/ipcMain/runtimeExecuteBash.test.ts:
   - Relaxed assertion on AI response text which is non-deterministic.
   - Added strict assertion on tool output to verify command execution success (the actual goal of the test).

2. tests/ipcMain/resumeStream.test.ts:
   - Replaced magic sleep(100) with proper event synchronization.
   - Now waits for 'caught-up' event before triggering resume, ensuring the event collector is ready.
