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.

  - nostr.grasp-default-set - only used during `ngit init`
- - nostr.relay-default-set      - must have at least 1 value, all events send to repo relays, user write and default relays
+ - nostr.relay-default-set      - used for profile discovery and account bootstrapping
