The goal of this epic is to create a manual trigger that allows users to signal when they have completed uploading reports for a specific commit using the Codecov CLI. This epic involves extending the UploadFinisher task to prevent notifications for regular uploads, and integrating the manual trigger into the CLI. This will streamline the report submission process and enhance the user experience for Codecov CLI users.
