extract grasp/maintainership helpers to lib and auto-accept on push

move apply_grasp_infrastructure, latest_event_repo_ref to lib/repo_ref.rs
and wait_for_grasp_servers + grasp_servers_from_user_or_fallback to a
new lib/accept_maintainership.rs so both binaries can share them.

add accept_maintainership_with_defaults which publishes the co-maintainer's
own Kind:30617 announcement with defaults (user grasp servers, shared
metadata from existing events) then waits for grasp server provisioning
and updates nostr.repo config and origin remote.

replace the push error block with a call to accept_maintainership_with_defaults
so pushing now silently accepts co-maintainership instead of failing.
