Wavelet Matrix Range Queries

Build a16-level wavelet matrix and answer equality, less-than and order-statistic range queries.

Build a16-level wavelet matrix and answer equality, less-than and order-statistic range queries. Up to 2048 unsigned16-bit values and 128 queries over half-open[start,end) ranges. Zero-based k returns null when it exceeds the selected range length, including empty ranges. Each level exposes its stable-partition bit string and zero count. Static in-memory data only; no persistent index, compression-ratio or logarithmic build-time claim. Supplied non-sensitive data only; no live account access, automated changes or certification. Profile 1.0.0: approximate non-integers use 12 significant digits; safe integers and declared integer strings are preserved.
