kglite 0.10.19

Pure-Rust knowledge graph engine — Cypher pipeline, snapshot/working CoW transactions, columnar/mmap/disk storage backends, optional dataset loaders (SEC EDGAR, Sodir, Wikidata). PyO3 wrappers live in the sibling kglite-py crate (the Python wheel); embeddable directly from any Rust binary without PyO3 in the dep tree.

//! Form S-3 — Shelf Registration Statement.
//!
//! Secondary offerings (post-IPO) under shelf registration. Concrete
//! offering terms land in subsequent 424B prospectus filings.
//!
//! ## Emits
//!
//! - `processed/offering.csv` — shelf-level capacity (max aggregate
//!   amount, securities allowed). Usually a "shell" without final
//!   terms — those come from companion 424B filings.
//!
//! ## Goalpost section
//!
//! See `kglite/datasets/sec/FEATURE_GOALPOST.md` §7 — S-3.
