test(e2e): test CLI in addition to jest integration

[oetr]

• previously, only Jest test was run in our e2e tests
• dependabot upgraded yargs to 18 (ESM-first) and nothing failed, even though node version14 and 16 should fail with this change

[Copilot]

Pull request overview

This PR strengthens end-to-end CI by adding a direct Jazzer.js CLI smoke test across multiple Node versions, ensuring incompatibilities (e.g., ESM-first yargs upgrades) are caught even when the Jest integration still passes.

Changes:

• Add an end-to-end npm script to run a minimal CLI fuzz invocation (fuzz:cli).
• Introduce a minimal CLI fuzz target (cli-smoke.cjs) used by the smoke test.
• Update the PR workflow to run the CLI smoke test for each Node runtime (14–24), and configure Dependabot to ignore yargs >=18.
