Function collect_php_files_gitignore

src/util.rs:274–314

Recursively collect all `.php` files under a workspace root, respecting `.gitignore` rules (including nested and global gitignore files). Used by Find References which walks the entire workspace root. Unlike [`collect_php_files`], this uses the `ignore` crate's [`WalkBuilder`] so that generated/cached directories listed in `.gitignore` (e.g. `storage/framework/views/`, `var/cache/`, `node_modules
