Embedding the core

The moraine crate is a plain Rust library: any tokio host can open a catalog and read or commit against it directly, with no DuckDB and no service in the path. The extension is one consumer of the core, not the center of gravity.

[dependencies]
moraine = "0.3"

The crate-root docs teach the API by worked example — snapshots, schemas, tables, and the transactional commit protocol:

• API documentation on docs.rs
• The crate on crates.io

Pre-1.0 semver: breaking changes bump the minor version.
