- internal/invite: Encode/Decode waste:<base64json{anchor,network}>
- proto: CmdGenerateInvite + EvtInviteGenerated + InviteString field
- ipc: track active network name; handle generate_invite (returns invite
string when joined to a network, errors if not joined or no anchor)
- daemon: --join <invite> flag — decodes anchor URL + network name,
sets anchor and auto-joins on startup
- tui: --join <invite> flag — extracts network name, skips -network
requirement; ctrl+i generates invite and shows it full-screen;
Esc dismisses the invite overlay
- FUTURE.md: document multi-network derived-identity design
