Add support for running multiple eval files by name

Hi there! 👋

I'd love to be able to run a set of specific test files by file path in much the same way as I would with other test runners or eval runners:

evalite ./src/system-prompt.eval.ts ./src/tools/search.eval.ts

Vitest uses the interface of vitest [...filters], allowing you to provide file name patterns, like so:

vitest basic

Runs tests on the following files:

basic.test.ts
basic-foo.test.ts
basic/foo.test.ts

This interface also allows you to provide multiple filters, supporting multiple verbatim paths to be provided to Vitest.
