Fix test failures: HMAC length check (P3), fast-check fround (P5)
Some checks failed
CI — P3 Alert / test (push) Failing after 15s

- P3: timingSafeEqual requires equal-length buffers; add length guard before compare
- P5: fast-check fc.float requires 32-bit floats; wrap min with Math.fround()
- All 5 Node products: 83 tests passing across 13 test files
