config — owner-wide defaults (default relay)

retalk config                                    # show ~/.retalk/config.json
retalk config --relay https://relay.example.com  # set the default relay
retalk config --relay ""                         # clear the default relay

Owner-wide (machine-wide), not per-session — so no --dir. The default relay is the last fallback: a --relay flag, RETALK_RELAY, and the relay saved in an identity at init all override it. retalk ships a built-in default of https://relay.retalk.dev, so a fresh setup can talk without configuring a relay. RETALK_HOME relocates the file.

Per-session identities still set their own relay at init; use this only to change the machine-wide fallback shared by all identities.
