…nerators New functions documented: - rnd_symbol_zipf(): Zipf/Power Law distribution for symbols - rnd_symbol_weighted(): explicit weight-based symbol distribution Random value generator improvements: - Add Quick Start example with timestamp_sequence - Add prominent warning about re-evaluation behavior - Fix typos, standardize formatting, improve examples Sequence generator restructure: - Merge timestamp-generator.md into row-generator.md - Add "Choosing the right function" comparison table - Document period string format (n, U, s, m, h, d) - Add inline comments explaining microsecond values Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
