chore: Bump to Node 24 LTS and setup-node v6

[andreiborza]

• Bump Node.js runtime from 20.19.2 to 24.14.1
• Bump actions/setup-node from v4.4.0 to v6.3.0
• Bump @types/node from ^20 to ^24
• Update Volta config to Node 24.14.1
• Add Node 24.x to CI test matrix

Important

actions/setup-node@v6 runs on the node24 Actions runtime, which
requires runner version v2.327.1 or later.
Self-hosted runners on macOS or Windows using an older runner version
will need to upgrade. Linux runners are unaffected.

GitHub-hosted runners are already compatible.

Closes: #312
