Commit Message

Add facet-assert crate for structural assertions without PartialEq

This crate provides `assert_same!` which compares values structurally
via Facet reflection, without requiring PartialEq or Debug.

Key features:
- No PartialEq required - uses Facet reflection
- Structural sameness - different types with same structure are "same"
- Smart diffs showing exactly which field at which path differs
- Opaque types fail with clear error messages

Example:
```rust
#[derive(Facet)]
struct Config { host: String, port: u16 }

let a = Config { host: "localhost".into(), port: 8080 };
let b = Config { host: "localhost".into(), port: 8080 };
assert_same!(a, b);  // No PartialEq needed!
```
