Printing Press Publish

Takes a CLI you've generated locally with printing-press and opens a pull request to the public library repo. It handles the full workflow: resolves which CLI you want to publish (by exact name, fuzzy match, or interactive picker), clones or updates your fork, commits the manifest and source files, and pushes a branch. One thing worth knowing is it actively prevents you from accidentally including the auto-generated mirror files that the library regenerates on merge, which saves you from pre-rejected PRs. The scope isolation is thoughtful too, it cleans up old repo clones when their source worktrees disappear so you don't accumulate garbage across temporary checkouts.
