github-common

Create a new GitHub repo or apply ghcommon house standards to an existing one. Use when the user says "create a new repo", "bootstrap a repo", "set up a new repo to our standards", "apply our standards to repo X", "make this repo compliant", "new action/library/service/cli repo", or wants merge settings, branch protection, labels, dependabot, and instruction files configured in one shot. Wraps gh repo create, applies repo-level settings (rebase-only, auto-merge, no delete) and branch protection on main, runs ghcommon's label and instruction-file sync scripts, seeds flavor-specific overlay files, and records the bootstrap in ghcommon/.github/bootstrapped-repos.json.
