Function extract_dependencies

pub fn extract_dependencies(
    project: &CargoProject,
    options: SourceOptions,
) -> Result<DependencyExtraction, ArchUnitError>

Parses selected Cargo targets and extracts Rust dependency references.

Internal module prefixes and renamed workspace dependencies resolve to workspace-relative files. Sysroot and declared third-party dependencies resolve to their Cargo-visible crate names. Parse, ambiguity, and unknown-name limitations are returned as diagnostics instead of aborting files.
