The eigen/ directory was a byte-identical copy of upstream libeigen/eigen tag 3.4.0 (commit 3147391d, the same release libCZI pins in cmake/ExternalEIGEN3.cmake). Replace the copy with a shallow git submodule (.gitmodules: shallow = true) for verifiable provenance and smaller fork. The Eigen3::Eigen interface config moves to eigen-cfg/Eigen3Config.cmake (the Eigen repo only ships the Eigen3Config.cmake.in template), and build.rs points Eigen3_DIR there.
