chore: drop Node 20.x from CI matrix, add Node 24.x

[pinecone-groundskeeper]

Problem

CI's build-and-test matrix tested node-version: [20.x, 22.x]. Node.js 20 ("Iron") reached end-of-life on 2026-03-24 and no longer receives security or bug fixes, so CI was validating the project against an unsupported runtime.

Solution

Updated the matrix in .github/workflows/ci.yml to [22.x, 24.x] — the two currently-supported Node LTS lines. Left the audit job's pinned node-version: 22.x as-is, per the issue's explicit reviewer's-call note.

Verification

Ran the CI steps locally on Node 24 (this sandbox's only available runtime): npm run lint, npm run format:check, npm run typecheck, and npm test all pass (23/23 tests). Could not exercise the Node 22.x leg or a real GitHub Actions run locally, but the change is a one-line matrix edit with no code-path dependency on Node version.

Follow-ups

None — scope was intentionally limited to the CI matrix per the issue.

Closes #32
