Provide mock codex binary in test runner for CI environments (v1.10.7)

Tests that call setup-rlcr-loop.sh or setup-pr-loop.sh fail in CI
because codex is not installed. These tests only need codex to pass
the command -v check and never actually invoke it. Create a no-op
mock codex in run-all-tests.sh when the real binary is absent.
