Adds rcfile_resolve_path() (rcfile.c/rcfile.h): resolves $XDG_CONFIG_HOME/xce_test/rc when set and non-empty, else $HOME/.config/xce_test/rc, else NULL. Standalone libc-only module mirroring the configcompare.c pattern; wired into xce_test_src and controller_unit_test_src, registered in controller_test.c's Unity runner. 6 unit tests in test_rcfile.c cover all XDG/HOME combinations plus a dedicated env-var save/restore isolation test, addressing the cross-test leak risk found during design review (controller_unit_test runs 80+ test files in one process). Adds the xce-test-rc-file spec (requirements/design/tasks/research), including design fixes from validation: getline()-based line reading (task 1.2, avoids truncating long rc-file lines) and the env-isolation requirement above.
