Fix drift=0: inline OPERA mel preprocessing, eliminate matplotlib/seaborn dependency

Fix: add matplotlib — OPERA src/util.py imports it at module level, causing zero embeddings and drift=0

Log OPERA preprocess result and exceptions to stderr for drift=0 diagnosis

Add norm logging to compute_cough_drift to trace zero-drift root cause

Add detailed stderr logging to trace drift=0 bug (bas_emb shape + drift value)

Fix thread-safety: serialize os.chdir() with lock to prevent cough drift=0 on concurrent requests
