AI Summary

This release introduces multi-field payload builders for testing and support for complex field types like `Option<Vec<T>>`. It also implements a configurable buffer limit to prevent memory issues and updates the Rust version requirement.

Key Highlights

Added multi-field multipart payload builders to `actix_multipart::test`
Added `MultipartForm` support for `Option<Vec<T>>` fields
Implemented a buffer limit (64KB) to prevent unbounded memory growth on malformed bodies
Minimum supported Rust version (MSRV) is now 1.88

Breaking Changes

Internal multipart parser buffering is now capped at 64KB (configurable via `MultipartConfig::buffer_limit`).

New Features

Multi-field multipart payload builders in `actix_multipart::test`
`MultipartForm` support for `Option<Vec<T>>` fields
