/**
 * FNV-1a 32-bit hash — fast, non-cryptographic content hash.

 * Used for cache keys, content fingerprinting, and provenance tracking.
 * Returns an 8-character zero-padded hex string.
 *
 * Shared across fixture-resolver, variable-resolver, and trace-store
 * to ensure consistent hash behavior. Uses unsigned right shift (`>>> 0`)
 * to keep the hash in unsigned 32-bit integer range.
