/**
 * Parse a RIFF/WEBP container into its constituent chunks.
 *
 * Each chunk's `data` is a `subarray` view into the input buffer — no
 * copy. This matters for large WebP files: the previous implementation
 * used `buffer.slice(...)` which copied each chunk's bytes, doubling
 * peak memory during decode of multi-megabyte input. Callers that
 * mutate chunk data should clone explicitly.
 *
 * Tolerates short/truncated input: instead of looping to negative
 * offsets or reading past EOF, we stop cleanly when the next chunk
 * header would extend beyond `buffer.length`.
