[eas-cli] Add `eas run` command

[sjchmiela]

Why

eas workflow:run .eas/workflows/deploy-to-production.yml is quite long.

eas run deploy-to-production is ✨.

How

• added an alias to the command
• changed how we resolve workflow file path from input (to support deploy-to-production).

Test Plan

Claude wrote tests which look sensible. I ran easd run basic-test in my local project.

> ~/Developer/test-local/mobile (test-5 [$✘!?]) easd run basic-test
