改用兩段判定取代中位數平滑: 精準實作穩定起步規則

依使用者定義: 穩定起步 = 一段移動連續 >=DEPART_SECONDS(8)秒、且其中沒有
>=STOP_SECONDS(4)秒的 GPS=0。作法:
 - smooth_speeds 改為只做『讀不到當0 + 物理過濾』,不再做中位數(避免視窗糊掉邊界)
 - find_keep_intervals 兩段: Pass A 短停(<4s)併入移動; Pass B 短移動(<8s)併入停止
 - 移除 depart_min_speed(速度門檻)與中位數,改用零模式判定,更乾淨且邊界精準
 - MIN_CONFIDENCE 0.7->0.5(門檻太高會濾掉真實 creep 讀數如 12@0.55)
實測 02: #11(原#9)精準剪到 19:15(符合使用者), #3 保留真起步, #4 排隊龜速全剪。
