v0.28.0

Added

• Composer plugin type: composer require jorgsowa/mir now triggers the binary download automatically without requiring manual script wiring. The composer.json type field is set to composer-plugin, and a Plugin class registers the install/update event handler.

Fixed

• Composer installer now embeds the target triple in the version marker, preventing a binary installed on one platform (e.g. macOS) from being reused on a different one (e.g. Linux in Docker). The shim error message for proc_open failures now mentions a possible architecture mismatch.
• Broken relative links in the error codes reference table (./ → ../) that caused 404s when navigating from the codes page to individual issue pages.
• Documentation corrections for ImplicitToStringCast, InvalidCast, UndefinedClass, InvalidScope, DeprecatedMethod, and DeprecatedMethodCall issue pages. Added missing UndefinedTrait (MIR0009) documentation page.
