Subject: [PATCH 2/2] fix(sh): propagate failed jumps as non-zero

builtin cd and custom $_ZL_CD can both fail after the guards pass (missing command, no search permission, vanished directory). The inner if masked the failure back to 0, and _ZL_ECHO would even print the stale directory. Append || return 1 to both branches.
