1//! Database + Analysis/AnalysisHost split (rust-analyzer pattern).
2//!
3//! `AnalysisHost` owns the mutable database; LSP write paths (`did_open`,
4//! `did_change`, workspace scan) go through the host. `Analysis` is a read-only
5//! view used by request handlers. Phase A keeps this minimal — cancellation and
6//! true snapshot semantics land in Phase E.
