arcature-cli 2026.2.0

//! The Arcature framework version (AP2.1-10).
//!
//! Reads the framework version from the workspace `arcature` crate's
//! `Cargo.toml`. This is the honest source: the version the app was compiled
//! against is the workspace's `arcature` version. The CLI avoids a direct
//! runtime dependency on the `arcature` facade crate (it depends on templates
//! + db, not the facade), so it parses the workspace `Cargo.toml` instead.
