chore(beads): name the tracker's remote by an alias, so this repo no longer says where it is (#46)

`.beads/config.yaml` named the private server that holds this repo's issue tracker. A public repo has no reason to say where that is.

The `sync.remote` line now names `beads-tracker`, an ssh alias that only the maintainer's machines resolve. The rest of that file and the "Where the tracker syncs" section in the agent instructions say "a private remote" and nothing more.

Nothing else changes. The tracker itself does not move, and syncing from the maintainer's machines works as before.
