@onlyworlds/sdk 4.30.0

Added

• A friend with only a link (keel #353, D111):
  • redeemJoin(code, { name?, agentName? }): redeems a join code that needs no account, at POST /join,
    sending no credential whatever key the client holds. The answer's kind tells the two apart:
    OwPlayerJoined (a read key, ow_r_, no PIN, and the Character the player reads as) or
    OwAgentJoined (a seat's write key, secret and .env lines). Shown once; the code is spent, so a
    lost answer means a new link. Every bad code is one 404.
  • createWorldLink(worldId, { reader: 'player', character? }): a player link, guest only; character
    is a Character's id or new (the default). OwWorldLink.character names it on the list.
  • player joins the kind of OwMe and OwMember.
• A client with no key: apiKey is optional. new OwV2Client() (or an empty key) has keyKind: 'none'
  and can call health, previewJoin and redeemJoin, which is what a friend with only a link has; any
  other call is a TypeError before anything is sent. Until now a key was required even for the routes
  that send none.
