feat(repo): validate create templates, publish local projects, verify edits

repo create --license NOPE returned Gitea's HTTP 500 internals. License,
.gitignore and label templates are now checked against the server's
lists, case-insensitively, and complete with Tab. --source DIR adds the
new repository as a remote of a local Git repository and --push pushes
its current branch; --public is the explicit opposite of --private, and
-d/-g/-l and the new alias follow gh. --trust-model now offers the names
Gitea accepts. A prompted name is confirmed with the visibility, owner
and host, and creation reports "✓ Created repository ..." and the URL.

repo edit --default-branch nope exited 0 without changing anything; the
branch must now exist. Edit gains --visibility, --enable-issues/-wiki/
-pull-requests/-projects, --allow-merge-commit/-squash/-rebase,
--delete-branch-on-merge, --default-merge-style and --add-topic/
--remove-topic, and reports which settings it changed.

repo migrate names the repository after the source URL, validates
--service before prompting, and reports the import with the URL.
