internal/ffi/ffi.go 的 cgo LDFLAGS 硬编码 -L target/debug，而 build-rust 用 --release（产物落 target/release），干净环境下 make build/test-go/ci 必然 报 cannot find -lbat_ffi。 - LDFLAGS 指向 target/release，并加 -Wl,-rpath 让产物运行时无需 LD_LIBRARY_PATH 即可定位 libbat_ffi.so；删除指向不存在目录的无效 CFLAGS -I（C 声明本就内联）。 - 新增 build-ffi target（cargo build --release -p bat-ffi），build-go 与 test-go 依赖它，确保链接前 release FFI 库已存在。 验证：make build-go 成功产出并可运行 bin/bat；make test-go 链接并通过； go vet（check-go）通过。 对应 issue #18 维护清单 1-6。 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
