Remove Node 20 support, harden engine requirements

[esimkowitz]

With our recent migration to PNPM 11 and the recent EOL for Node 20, I'm dropping Node 20 support. I'm also using this opportunity to harden the engine requirements and add a new release test run to ensure compatibility with Node 24.

---

Note

Medium Risk
Medium risk because it introduces a breaking runtime requirement bump (Node >=22) and changes release/CI matrices to test/publish against new Node versions, which could affect build and publishing behavior.

Overview
Updates runtime support to require Node.js >=22 (and declares minimum versions for Deno and Bun) and adds a repo-wide .node-version as the pinned primary Node version.

GitHub Actions workflows are adjusted to use .node-version for installs, and the release workflow now tests artifacts against Node 22 and 24 while only running the full cross-runtime suite on the primary Node version.

pnpm configuration is tightened by moving minimumReleaseAge to pnpm-workspace.yaml and switching the Node test runner invocation from npx tsx to pnpm exec tsx.
