1//! Glob pattern extraction helpers for `WorkspaceProvider::FindFiles` calls.
2//!
3//! VS Code passes glob patterns in several shapes depending on the caller:
4//! - Bare string: `"**/*.rs"`
5//! - `RelativePattern` object: `{ base, pattern }` or `{ baseUri, pattern }`
6//! - Legacy serialised form: `{ value: "**/*.rs" }`
7//!
8//! These helpers normalise all shapes to a `String` and extract the optional
9//! `base` directory for bounded walks.

15/// - Object with `pattern` field (VS Code `RelativePattern`).
16/// - Object with `value` field (legacy serialised form).
17/// - Object with `Pattern` field (PascalCase variant).
