Fix remaining lint errors (formatting)

- Fixed formatting in `crates/rustapi-openapi/src/spec.rs` and `crates/rustapi-rs/examples/native_openapi_demo.rs` by running `cargo fmt --all`.
- Removed trailing whitespace in `crates/rustapi-macros/src/derive_schema.rs` that was causing `rustfmt` to fail.

 ## [Unreleased]
 
-## [0.1.203] - 2026-01-30
-
-### Native OpenAPI 3.1 - Zero External Dependencies 🎯
-
-This release marks a **major architectural shift**: RustAPI now generates OpenAPI specifications natively, removing the `utoipa` dependency entirely.
-
-#### Breaking Changes ⚠️
-
-- **Removed `utoipa` dependency**: Types no longer need to implement `utoipa::ToSchema`. Instead, implement `RustApiSchema` trait.
-- **OpenAPI version upgraded**: Specifications now generate as **OpenAPI 3.1.0** (previously 3.0.3) with full JSON Schema 2020-12 support.
-- **Schema trait rename**: `Schema` derive macro now generates `impl RustApiSchema` instead of `impl ToSchema`.
-
-#### Migration Guide
-
-```rust
-// Before (utoipa-based)
-use utoipa::ToSchema;
-#[derive(ToSchema)]
-struct User { ... }
-
-// After (native)
-use rustapi_rs::prelude::*;
-#[derive(Schema)]  // Now generates RustApiSchema impl
-struct User { ... }
-```
-
-### Added
-
-- **`RustApiSchema` trait**: New trait in `rustapi-openapi` for native JSON Schema generation
-- **`#[derive(Schema)]` macro**: Generate `RustApiSchema` implementations at compile-time
-- **`JsonSchema2020` struct**: Full JSON Schema 2020-12 compatible schema representation
-- **`SchemaCtx`**: Context for managing component deduplication and $ref generation
-- **Deterministic output**: All maps use `BTreeMap` for stable, sorted JSON output
-- **Comprehensive primitive support**: i8-i128, u8-u128, f32/f64, bool, String with proper format annotations
-- **Generic type support**: `Vec<T>`, `Option<T>`, `HashMap<String, T>` with proper schema composition
-- **Nullable types**: OpenAPI 3.1 native `type: ["string", "null"]` syntax for `Option<T>`
-
-### Changed
-
-- **OpenAPI version**: `3.0.3` → `3.1.0`
-- **Swagger UI**: Now served from CDN (unpkg) instead of bundled assets, reducing binary size
-- **`OpenApiSpec`**: Refactored to use `BTreeMap` throughout for deterministic serialization
-- **Extractor schemas**: `Json<T>`, `ValidatedJson<T>`, `Query<T>` now use `RustApiSchema` bound
-- **Component registration**: `spec.register::<T>()` now uses `RustApiSchema` trait
-
-### Removed
-
-- **`utoipa` crate dependency**: ~500 fewer transitive dependencies
-- **`rustapi-openapi/src/v31/` module**: Experimental v31 code replaced by unified implementation
-- **Bundled Swagger UI assets**: `swagger-ui-bundle.js`, `swagger-ui-standalone-preset.js`, `swagger-ui.css` removed
-- **Benchmark servers**: Removed temporary benchmark-related server implementations
-
-### Fixed
-
-- **Compile-time schema generation**: Schemas are now generated at compile-time via proc macros
-- **Circular reference handling**: `SchemaCtx` properly handles recursive types with $ref
-- **Field optionality**: `Option<T>` fields correctly marked as non-required in struct schemas
-
-### Documentation
-
-- Updated [native_openapi.md](docs/native_openapi.md) with implementation status
-- Added migration examples in cookbook
-- Updated crate-level documentation

 # RustAPI Release History
 
-## v0.1.203 - Native OpenAPI Revolution (2026-01-30)
-
-### 🎯 Zero-Dependency OpenAPI Generation
-
-This release marks a **major architectural milestone**: RustAPI now generates OpenAPI specifications **natively**, completely removing the `utoipa` dependency.
-
-#### Why This Matters
-
-| Metric | Before (utoipa) | After (native) |
-|--------|-----------------|----------------|
-| Transitive deps | ~500+ | ~50 fewer |
-| OpenAPI version | 3.0.3 | **3.1.0** |
-| JSON Schema | Draft-07 | **2020-12** |
-| Output stability | HashMap (random) | **BTreeMap (sorted)** |
-
-### ⚠️ Breaking Changes
-
-```rust
-// Before (v0.1.202)
-use utoipa::ToSchema;
-#[derive(ToSchema)]
-struct User { ... }
-
-// After (v0.1.203)
-use rustapi_rs::prelude::*;
-#[derive(Schema)]  // Now generates RustApiSchema
-struct User { ... }
-```
-
-### ✨ New Features
-
-- **`RustApiSchema` trait**: Native trait for JSON Schema generation
-- **`#[derive(Schema)]` macro**: Compile-time schema generation
-- **OpenAPI 3.1.0**: Full support for latest spec including:
-  - `type: ["string", "null"]` for nullable types
-  - JSON Schema 2020-12 dialect
-  - Webhooks support
-  - Security schemes
-
-### 🔧 Technical Improvements
-
-- **Deterministic output**: All maps use `BTreeMap` for reproducible JSON
-- **CDN-based Swagger UI**: Reduced binary size by loading from unpkg
-- **Compile-time generation**: Schemas generated at build time, not runtime
-- **Circular reference handling**: Proper `$ref` management for recursive types
-
-### 📦 Removed
-
-- `utoipa` crate dependency
-- Bundled Swagger UI assets (~2MB saved)
-- Experimental v31 module (replaced by unified implementation)
