Remove multiple Pine Script indicators: SSFDSP, STARCHANNEL, STBANDS, STC, UBANDS, UCHANNEL, VWAPBANDS, and VWAPSD. These indicators were deleted to streamline the library and remove unused or redundant code.

+// ── Functions ──────────────────────────────────────────────────────────
+// @function Calculates the Moving Median Filter over a sliding window.
+//   A nonlinear filter that outputs the median of the last N values.
+//   Robust to impulse noise and outliers while preserving edges/steps
+//   better than any linear filter (SMA, EMA, etc.).
+//   Uses circular buffer + insertion sort for O(N log N) per bar.
+// @param source Series to filter
+// @param period Window size (must be > 0)
+// @returns Median-filtered value, valid from bar 1
