Basic workflow

This workflow runs Junie CLI when the user adds a comment to an issue or a pull request tagging @junie-agent, mentions @junie-agent in the issue title or description, or submits a PR review that has @junie-agent tagged.

When finished, Junie CLI creates a new PR with all the necessary code changes. You can either approve the changes and merge the PR, or trigger Junie CLI to iterate on the task by mentioning @junie-agent and providing follow-up instructions in a comment to this PR.
