Framework: Update the AI development job to Node.js 24

[manzoorwanijk]

What?

See #80812. Follow up to #82370. Moves the agent-development job in static-checks.yml off Node.js 22 and onto the repository version, and reuses the setup-node action there.

Why?

The Node.js 24 upgrade missed this job: its own actions/setup-node pin and hardcoded matrix versions kept CI testing the eval package on a Node version the repository no longer supports.

How?

The job no longer picks a Node version at all: the matrix is just the three operating systems, and ./.github/setup-node takes the version from .nvmrc. Node 26 coverage goes with it, and unit-test.yml and the check job still run it. test/ai-development no longer pins an older Node than the repository, so its own .nvmrc is gone and engines.node follows the root. The eval package's tree is excluded from the shared node_modules cache, since it is not a workspace and installs from its own lockfile. The added root install is why the timeout goes from 15 to 30 minutes.

Testing Instructions

1. Confirm the AI development tests pass on all three operating systems in this PR's checks.
2. Locally: nvm use && PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1 npm ci --prefix test/ai-development && npm --prefix test/ai-development run test:utils && npm --prefix test/ai-development run validate.
