vector_sdk 0.4.0

//! A bot that OWNS a Concord v2 community. On startup (with `VECTOR_CREATE=1`)
//! it creates the community, prints a shareable invite link, optionally
//! Direct-Invites an npub, then greets and echoes in its channels.
//!
//! Run:
//! ```sh
//! VECTOR_NSEC=nsec1... VECTOR_CREATE=1 cargo run -p vector-sdk --example v2_community_bot
//! # optionally also: VECTOR_INVITE_NPUB=npub1...
//! ```
//!
//! The community and its invites are on the modern protocol, byte-compatible
//! with Soapbox/Armada — the exact same discord.js-style API as a v1 bot; the
//! SDK routes to v2 under the hood.
