feat: add tight_layout wrapper with PYAUTO_FAST_PLOTS env var#254
Conversation
When PYAUTO_FAST_PLOTS=1, skip plt.tight_layout() in all subplot functions. This avoids expensive matplotlib font discovery and text metrics computation (~0.5-1s per subplot figure), cutting smoke test times significantly while preserving full code coverage.

plt.tight_layout()is the #1 plotting bottleneck in smoke tests — ~0.5-1s per subplot figure due to matplotlib font discovery and text metrics. Skipping it saves ~3.5s per script while preserving full code coverage.Test plan
