known-issues: two fixed entries (chunk dimensions of 2^32 or more were
refused; a 4 GiB unfiltered chunk was held several times when written),
the open "Chunks of 4 GiB or more: limits" updated (LZ4/Zstd tested end
to end, memory figures of 2026-09-29) and the open-issues table in sync.
CHANGELOG (Unreleased) entry with the public API changes and the peak
RSS measurements; README capability table. The wasm package test lists
the new fixture and expects an Overflow error reading its chunks.
