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.

+//@function Calculates RVGI — momentum oscillator comparing close-open vs high-low
+//@param period SMA smoothing period for the SWMA-weighted numerator/denominator
+//@returns [rvgi, signal] RVGI value and its 4-bar SWMA signal line
+//@description RVGI measures the conviction of a price move by comparing closing
+//  strength to the full range:
+//    Step 1: SWMA(close-open, 4 bars) with weights [1/6, 2/6, 2/6, 1/6]
+//    Step 2: SWMA(high-low, 4 bars) with same weights
+//    Step 3: SMA(step1, period) / SMA(step2, period) → RVGI
+//    Step 4: SWMA(RVGI, 4 bars) → Signal line
+//  The SWMA (Symmetrically Weighted Moving Average) uses fixed 4-bar kernel:
+//    swma(x) = (x[3] + 2*x[2] + 2*x[1] + x[0]) / 6
+//  SMA sums use O(1) circular buffers with §3 count-based warmup.
+//  Defensive division: denominator == 0 returns 0.
+//  Crossovers of RVGI and Signal indicate momentum shifts.
+//  In uptrends, closes tend near highs → positive RVGI; downtrends → negative.
