CI: lint workflow uses `npm install ci` instead of `npm ci`

[fallintoplace]

Summary

The lint job in .github/workflows/lint-and-test.yml runs npm install ci instead of npm ci.

Why this is a problem

npm install ci does not perform a clean lockfile-based install. It is interpreted as npm install <package>, so the lint job is not using the intended CI install path and may run against a dependency tree that differs from the test job.

The test job in the same workflow already uses the correct command:

• lint job: npm install ci
• test job: npm ci

Location

• .github/workflows/lint-and-test.yml

Suggested fix

Replace the lint step with:

npm ci

That keeps lint/typecheck aligned with the lockfile and with the existing test job setup.
