A binding and every row of its project's code-shape ledger are keyed by the
repo's remote. A rename on the forge changes the remote, so binding the new name
started an empty ledger beside the old one and left every judgment behind.
bind_repo now takes moved_from, the old remote. Its binding and the project's
ledger rows move to the new key in one transaction, and the reply says how many
shapes moved. The move is refused when:
- the old name isn't bound to that project;
- the new name is already bound;
- the project already has a ledger under the new name.
Each refusal leaves both names exactly as they were.
