fix: bare except (#1159)

Bare `except:` catches SystemExit and KeyboardInterrupt, which can:
- Mask Ctrl+C handling during long optimization runs
- Hide critical system signals
- Make debugging harder

Replacement by `except Exception:` preserves the same error handling while respecting
system-level exceptions.
