feat: use fallback relays for bootstrapping only

- Add --relay flag to 'ngit account create' allowing users to specify
  relay URLs (repeatable). Defaults to relay-default-set when not provided.
- Remove fallback relays from fetch when repo context exists (repo
  coordinate provided). Only use them for bootstrapping (profile discovery
  with no repo context).
- Remove fallback relays from publish when repo or user relays exist.
  Only use them when neither is available (e.g. new account signup).
- Update --customize help text to reflect new relay-default-set behavior.
