libtmux(fix[logging]): remove exc_info from options parse warnings

why: exc_info=True on WARNING-level parse failures produces noisy
tracebacks for expected edge cases (non-string option values). The
structured extra fields already provide sufficient context.
what:
- Remove exc_info=True from all 5 logger.warning() calls in options.py
