test(cli): add comprehensive CLI argument parsing tests
Add 26 new BATS tests validating all CLI flags in ralph_loop.sh: - Help flag tests (2): --help, -h short flag - Flag value tests (6): --calls, --prompt, --monitor, --verbose, --timeout - Status flag tests (2): --status with/without status.json - Circuit breaker tests (2): --reset-circuit, --circuit-status - Invalid input tests (3): unknown flag, invalid timeout, invalid format - Multiple flags tests (3): combinations, all flags, early exit - Flag order tests (2): verify order independence - Short flag tests (6): -c, -p, -s, -m, -v, -t equivalence Test strategy uses --help as early-exit escape to validate parsing without triggering main loop execution. Closes #10
