Add diagnostics to pin down where the INIT_NOTIFY fd handoff hangs: - init/src/service.rs: log read_pipe fd and call_ro results - daemon/src/lib.rs: log cap_fd, write_pipe, and call_wo result - logd/src/main.rs: explicit ready_sync_scheme result and setrens fallback These are temporary diagnostics for the boot-hang investigation.
