Method init_monorepo

src/server.rs:1638–1786

Initialize a monorepo workspace (no root `composer.json`, but subprojects with their own `composer.json` were discovered). Each subproject is processed through the Composer pipeline (PSR-4, classmap, autoload files, vendor packages). After all subprojects are processed, a gitignore-aware full-scan picks up loose PHP files outside any subproject directory.

        subprojects: &[(PathBuf, String)],
        php_version: crate::types::PhpVersion,
        progress_token: Option<&NumberOrString>,
    )
