InspectValue.rs

1//! Configuration value introspection across all scopes.
2//!
3//! Implements `InspectConfigurationValue` for `MountainEnvironment`.
4//! Unlike `GetValue` (which reads the merged cache), this function
5//! re-reads each configuration layer individually so callers can see
6//! exactly which scope provides a value:
7//!
8//! | Field | Source |
9//! |---|---|
10//! | `DefaultValue` | Extension `contributes.configuration` defaults |
11//! | `UserValue` | `<app-config>/settings.json` |
12//! | `WorkspaceValue` | workspace `settings.json` |
13//! | `EffectiveValue` | Workspace → User → Default (first non-`None`) |
14//!
15//! Returns `None` when the key is not present in any scope. Dot-notation
16//! keys (e.g. `"git.enabled"`) are resolved by splitting on `.` and
17//! walking the nested JSON tree, matching `GetValue`'s traversal.
