feat: v0.3.0d — add PR checks, iostreams, aliases, and broad enhancements

Add PR checks command, iostreams/text packages for colored table output,
top-level run/workflow aliases matching gh CLI structure. Enhance actions,
issues, PRs, releases, repos, labels, milestones, and wiki commands with
improved flags, JSON output, and error handling.
