Add the local project, framework submodule, hooks and templates

After the repositories and the mirror, the script now creates the local
project: the directory, git on main, credential-free origin (and github)
remotes, and the license history from Gitea. Then it adds the framework as
a submodule over SSH, installs its skills and git hooks once (plan gate
optional), and copies the AGENTS.md and artifact registry templates.

Nothing is overwritten without a yes: an existing directory, core.hooksPath,
AGENTS.md or docs/artifact-registry.md each ask first (default no). Without
SSH the framework steps can only be skipped, after a yes. No commit is made
in the new project. New optional config key FRAMEWORK_REPO.

New library files git.sh, localproject.sh and framework.sh. Tests run real
git against local bare repositories that stand in for Gitea and the
framework, with a private git configuration (769 checks). The README is now
the full guide.
