fix+test: improve test suite, fix 2 bugs found by tests
Bugs fixed in production code: - compare.sh: Python truthiness on 0.0 — `if b_val` was False for 0.0 t/s, displaying it as a dash instead of "0.0". Fixed with `is not None` checks. - compare.sh: ZeroDivisionError when computing delta % with 0.0 baseline. Test improvements (review findings): - detect.bats: kernel param tests now use real detect_kernel_param logic pattern (not a separate reimplementation). Added non-GiB-aligned RAM test, device ID without 0x prefix, empty firmware version, llama-bench detection, detect_total_physical_ram_kb tests. - benchmark_compare.bats: assert delta percentages (+20.0%, -25.0%, 0.0%), test 0.0 t/s edge case, test per-directory error messages, test config change detection with specific field assertions. - log_metrics.bats: add assert_success, --help test, timestamp format validation. Remove unused mock sysfs setup. - common.bats: fix data_dir test, remove redundant assertion, add cleanup. - test_helper.sh: remove unused FIXTURES_DIR. - Remove empty tests/fixtures/ directory. 94 tests, all passing.
