Subject: [PATCH] refactor: extract omnigraph-config crate from
 omnigraph-server

Move config.rs (schema + loader + resolvers) into a new clean-leaf crate
(serde/serde_yaml/clap/color-eyre). The server aliases it via
`pub use omnigraph_config as config;` so every internal `config::` path and
the `pub use config::{...}` re-exports resolve unchanged. No behavior change;
the 12 config tests move verbatim and pass. First step of RFC-002 V0.
