/add-friend

Append a new entry to .friends[] in $CLAUDE_PA_HOME/config.json. Each entry looks like:

{
  "name":  "Alex",
  "phone": "+972501234567",
  "role":  "a coworker",
  "vapi":  { "assistant_id": null, "phone_number_id": null }
}

name and phone (E.164) are required. role is what the dispatcher assistant uses to set tone and explain the relationship to the callee (defaults to "a friend of the user"). vapi.* overrides are optional — omit to inherit from the top-level vapi block.

Use jq to write atomically — read the current config, append the entry, write to a tmp file, then mv over. Don't blow away unrelated fields.

After adding, confirm by reading .friends[].name back and listing names to the user.
