//! Build the top-level RO-Crate for a hosted web/ directory.
//!
//! Scans `<web-dir>/data/*/ro-crate-metadata.json`, hoists each
//! per-dataset crate's structured properties into a single
//! `<web-dir>/ro-crate-metadata.json`, and writes the page-level
//! WebApplication / Person / SoftwareSourceCode identity entities
//! into the same graph. Used by the Pages workflow after dataset
//! generation so the deployed bundle has a fresh top-level crate
//! reflecting whatever datasets are present.
//!
//! Usage:
//!
//! ```sh
//! cargo run --release --bin build_web_rocrate -- \
//!     --web-dir web/ratdb/ \
//!     --page-url https://ratdb.app.pirogov.de/
//! ```
