/**
 * Chunking strategies for the streaming-parser invariant suite.
 *
 * Each strategy slices the *same* source text into an append-only chunk
 * sequence. The union of all strategies is designed to stress the parser's
 * boundary handling: `per-code-unit` deliberately splits UTF-16 surrogate pairs
 * (the hardest case — a chunk boundary can land inside a single emoji), while
 * the seeded strategies exercise arbitrary mid-token cuts reproducibly.
 *
 * Determinism is a hard requirement: no `Math.random`, no `Date.now`. The
 * seeded strategies use a tiny inline LCG so every run produces byte-identical
 * chunk boundaries.
