remove the hive-c0re forge-credential chain nothing reads any more

Browse source 
With no nix build on the hive, the boot publish of the forge token for nix has no reader. Removes the ForgeSweep node, the token file, the git credential helper and hive-c0re's forge gitconfig sections.

A store that holds no facts, or that doesn't answer, leaves the files as they stand, and a hive that never got them has `hive-priv` answer `not available`. |

Each `internal/meta` read and each boot rewrites the copy when it differs; where they differ after a rotation, a build that starts before the next read fails to authenticate, and a retry reads the new token |
| this hive's forge read token | `swarm-controller`, into the secret store at `swarm/hives/<hive>/forge/token`, for the `hive-<hive>` account; a pass at start and every five minutes re-mints a missing or stale token | `hive-c0re` reads it under the hive's own store identity for each forge read, and hands it to the `git` commands it runs.

A hive whose agents have no credential yet (an older controller) has an empty file: every login fails and the self-check reports `ok=false`; an agent without one sends none, so it goes direct |
