Method get_file_content

src/util.rs:1499–1522

Get the content of a file by URI, trying open files first then disk. This replaces the repeated pattern of locking `open_files`, looking up the URI, and falling back to reading from disk via `Url::to_file_path` + `std::fs::read_to_string`. Three call sites in the definition modules used this exact sequence.
