Improve documentation references

Improve Rust documentation readability by updating the format of all reference links from the existing format:

```rust
/// # References
///
/// See: <https://docs.oracle.com/javase/specs/jvms/se24/html/jvms-4.html#jvms-4.4.7>
```

to:

```rust
/// # References
///
/// - [JVM Specification §4.4.7](https://docs.oracle.com/javase/specs/jvms/se24/html/jvms-4.html#jvms-4.4.7)
```
