chore(main): release 4.0.0

[cheminfo-bot]

🤖 I have created a release beep boop

4.0.0 (2026-08-28)

⚠ BREAKING CHANGES

• a substructure query is matched as its idCode on every path, so a molfile bond query feature that getIDCode drops no longer widens the match. The pooled path already behaved this way, so search() answered differently depending on how many candidates filled a batch; it now gives one answer.

Performance Improvements

• verify and fingerprint with openchemlib-search-wasm (706f82f)
