5.1.0

• Introduced a runtime detector extension API with priority sorting, cleanup helpers, and automatic pipeline integration for custom signature detectors.

• Added comprehensive README guidance that walks through registering repository mappings, attaching extensions, and composing bespoke detector pipelines.

• Refreshed the Font Awesome icon mapping and expanded PHPUnit coverage with reusable recording doubles to lock in icon heuristics and extension behaviour.

5.0.0

feat: modularise MIME detection and document extension workflow

• replace the monolithic detector with a detection context, pipeline coordinator, and category-specific signature detectors that cache and return rich match objects
• harden the façade with guarded file handling, hash helpers, base64 URI fallbacks, and repository-driven MIME/extension lookups backed by a bi-directional map
• refresh the README with a clearer quick start, lookup examples, and a step-by-step guide for registering custom detectors and mappings
• add focused exception factories and byte-cache validation to signal unreadable files and support exhaustive test coverage
• add support for ~70 new file types
