/**
 * Greedy CTC decoding for PaddleOCR recognition output.
 *
 * The model emits per-timestep softmax probabilities over the character
 * dictionary plus a blank token (index 0).  Greedy decoding collapses
 * consecutive repeats and drops blanks to produce the final string.
 * Confidence = mean of max probabilities at non-blank timesteps.
 *
 * Vocab mapping (from loadVocab):
 *   index 0      = blank
 *   index 1..N   = character_dict entries
 *   index N+1    = space
