Chore — major upgrade of hashery (2 → 3) for @keyv/bigmap.

Versions

• hashery 2.0.0 → 3.0.0 (@keyv/bigmap)

Breaking notes

hashery v3's breaking changes are runtime/toolchain only — no public API changes:

• Minimum Node.js raised to ≥22.18. keyv already requires this (.nvmrc = 24, root engines.node = >= 22.18.0).
• Internal hookified bumped to 3.x. keyv is already on hookified@3.0.1.

@keyv/bigmap only re-exports the Hashery class (export { Hashery } from "hashery"), and the class API is unchanged, so no code changes are required.

Tests

• pnpm build passes for @keyv/bigmap
• pnpm test:ci passes (biome + 54 tests)
• Sanity-checked the re-exported API: new Hashery().toNumberSync(...) and new Hashery({ defaultAlgorithmSync: "fnv1" }) work as documented in the README

Runtime phase — breaking major (hashery).

Code Review

This pull request updates the dependency hashery from version ^2.0.0 to ^3.0.0 in core/bigmap/package.json and updates the lockfile pnpm-lock.yaml accordingly, including updating hashery's dependency hookified to version 3.0.1. There are no review comments, and I have no feedback to provide.
