Keep the intentional top-level Exception handler in testSimulator() so ordinary simulator failures still produce exit code 1 while KeyboardInterrupt and SystemExit propagate. The repository does not currently configure a check that requires a suppression here; add a targeted suppression only if a configured lint check later flags this intentional handler.

In `@meshtastic/test.py` at line 208, Keep the broad Exception handler in
testSimulator() so ordinary simulator failures still produce exit code 1 while
KeyboardInterrupt and SystemExit propagate; add a targeted BLE001 suppression on
that handler with a brief rationale comment.

Apply the same fix in `@meshtastic/util.py` at line 312: The repository-wide
suppression guidance is incorporated into the consolidated comment.
