v2.0.1

Added

• On dmage auth, the CLI adopts the server's advertised name (DOTMAGE_SERVER_NAME)
  as the local server name — no more manual dmage server rename after joining.
• dmage clean --server <name> wipes a single server (key + tokens + config entry);
  the global dmage clean now warns loudly before wiping every server.

Changed

• Global dmage clean points to dmage server rm / --server for single-server removal.
