Enum SqliteConnectionManager 

pub enum SqliteConnectionManager {
    File(PathBuf),
    SharedMemory {
        uri: String,
    },
}

A minimal r2d2::ManageConnection for rusqlite. Hand-written instead of depending on the r2d2_sqlite crate: that crate pins its own rusqlite version, which never lines up with the rusqlite version ling-ai already pulls in transitively (via the burn ML framework) — and two different rusqlite/libsqlite3-sys versions can’t coexist in one Cargo.lock (both declare links = "sqlite3"). r2d2 itself has no sqlite dependency, so implementing this ourselves keeps us on exactly one rusqlite version, chosen by us, everywhere in the workspace.
