fix(ci): drop PHP 8.0 and 8.1 from CI matrix

Both versions are EOL and phpbench 1.6.1 requires PHP ^8.2, causing
composer install to fail on older PHP versions.

fix(compat): add explicit type hints for PHP 8.4+ compatibility

- Add return type `bool` to __call() magic method in MobileDetect.php
- Remove unnecessary @ error suppression in prepareVersionNo()
- Add explicit parameter type hints to all test methods that lacked them
- Remove redundant isset() and is_string/is_bool checks made obsolete by typed params

fix(deps): pin composer dependencies to exact versions

Replaced caret (^) range constraints with exact version pins in
composer.json. Also trimmed CLAUDE.md.
