FIR + ICA 正常人 Alpha 三種 Baseline 指標

使用 FIR+ICA 後分割資料，針對每位正常人受試者繪製 ERD/ERS%、baseline-normalized dB change、Z-score bandpower 三種 Alpha 8-13 Hz 腦拓圖。此版不做統計檢定遮罩。

計算方式

baseline 為 -1.5 到 -0.5 秒；每個時間窗使用 Welch PSD 計算 8-13 Hz bandpower。ERD/ERS% = 100 * (power - baseline) / baseline；dB change = 10 * log10(power / baseline)；Z-score bandpower = (power - baseline_mean) / baseline_std，其中 baseline_mean/std 由該受試者、該條件通過 artifact filter 的 baseline trial 分布計算。

每張圖使用全部有效 trial 的 10% trimmed mean。輸出檔：used_trials_by_subject.csv、condition_trial_stats.csv、alpha_metric_summary.json。
