Chore: Upgrade Workflows to Node 24

[GODrums]

Upgrades all workflows to Node 24. Tested builds locally using ACT.

Github's statement:

Node.js 20 actions are deprecated. The following actions are running on Node.js 20 and may not work as expected: actions/checkout@v3, actions/setup-node@v3. Actions will be forced to run with Node.js 24 by default starting June 2nd, 2026. Please check if updated versions of these actions are available that support Node.js 24. To opt into Node.js 24 now, set the FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true environment variable on the runner or in your workflow file. Once Node.js 24 becomes the default, you can temporarily opt out by setting ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/

Note

Low Risk
Low risk CI-only change that updates workflow runtimes/actions and switches installs to npm ci; main risk is pipeline breakage if Node 24 or lockfile assumptions differ.

Overview
Upgrades CI/release workflows to Node.js 24 by updating workflow matrices and moving actions/checkout/actions/setup-node to @v6.

Standardizes dependency setup by enabling setup-node npm caching and using npm ci (separating install from build/lint where applicable), including in release and version-bump (upgrade.yml) automation.
