3//! Glob pattern extraction helpers for `WorkspaceProvider::FindFiles` calls.
4//!
5//! VS Code passes glob patterns in several shapes depending on the caller:
6//! - Bare string: `"**/*.rs"`
7//! - `RelativePattern` object: `{ base, pattern }` or `{ baseUri, pattern }`
8//! - Legacy serialised form: `{ value: "**/*.rs" }`
9//!
10//! These helpers normalise all shapes to a `String` and extract the optional
11//! `base` directory for bounded walks.

19/// - Object with `Pattern` field (PascalCase variant).
