Switon's CAPTCHA challenge, proof, and action-guard layer.

Highlights
----------

[](#highlights)

- **Challenge and verification flow:** generate a CAPTCHA, then verify the returned proof.
- **Standard request fields:** `CaptchaProofResolver` reads the usual CAPTCHA key and code fields.
- **Protected actions:** `#[CaptchaRequired]` blocks an action until proof is valid.
- **Image backends:** the package includes GD and Imagick adapters for image generation.
- **Observable checks:** creation, verification, and failure activity can be observed.

Installation
------------

[](#installation)

```
composer require switon/captcha
