Function resolve_strategy

src/formatting.rs:99–185

Resolve the formatting strategy from config, Composer metadata, and the workspace root. Resolution rules: - If `config.is_disabled()` (both tools set to `""`) → `Disabled`. - If either tool has an explicit non-empty path in config → `External` with those tools. - If `composer_json` has `friendsofphp/php-cs-fixer` or `squizlabs/php_codesniffer` in `require-dev` → `External`, resolving paths via th
