fix(ci): stabilize snapshot test and double CLI test timeout

- Add [GRAPH_PATH] filter to run_output_filters so dry_run_simple
  snapshot is path-independent
- Double fabro-cli slow-timeout (3s → 6s) to prevent ps test timeouts
- Preserve cloud sandboxes; bump snapshot to fabro-v7 with 8 CPU / 16GB
