Disk-backed cache for JSON Schema validation results. Caches the outcome of validating a file against a schema so that unchanged files can skip re-validation on subsequent runs.

Part of the [Lintel](https://github.com/lintel-rs/lintel) project.

## How it works

Each cache entry is keyed by a SHA-256 digest of the file contents and schema URI. When a file hasn't changed since the last run, the cached validation result is returned instantly — no parsing or schema evaluation needed.

## Usage

```rust
use lintel_validation_cache::{ValidationCache, schema_hash, ensure_cache_dir};

let cache = ValidationCache::new(ensure_cache_dir(), false);

// Compute a schema hash once per schema group
let schema = serde_json::json!({"type": "object"});
let hash = schema_hash(&schema);

// Cache key = SHA-256(file_content + schema_hash + validate_formats)
let key = ValidationCache::cache_key("file contents", &hash, true);
drop(key);
```
