Pull request overview

Adds consumer-side TypeScript checks to validate @rspack/dev-server public declarations under both bundler and NodeNext module resolution modes, and wires these checks into the repo’s test workflow.

Changes:

• Added two consumer-style type-test projects (resolution-bundler and resolution-nodenext) with skipLibCheck: false.
• Added a tests workspace script to run tsc against both type-test projects.
• Updated root test flow to run the new test:type step before rstest.
