{ enum: true } option for queries or perhaps Model.validate

### Prerequisites

### 🚀 Feature Proposal

Currently, when you query for values not included in an enum, no warnings or errors are thrown. We have `strictQuery` which checks the keys, but we don't have something similar for values.

### Motivation

Sometimes when working on multiple project with similar designs, names can be confused i.e. `done` versus `completed` or `in_progress` vs `in-progress`

### Example

`TestModel.find(filter, { enum: true });`

Start by reading the existing strictQuery behavior and enum validation paths referenced in the proposal, then compare the suggested TestModel.find(filter, { enum: true }) usage with the Model.validate alternative. Done requires a settled scope and design for detecting values outside an enum, including whether queries, validation, or both should report them.
