feat(#66): CI invariant test scaffold [DELTA]
- Add invariant_tests.zig with 42 test points (7 formats × 6 invariants) - I1: Roundtrip identity (decode(encode(x)) == x) - I2: Sign bit preservation - I3: Exponent monotonicity - I4: Mantissa precision - I5: NaN propagation - I6: Infinity handling - Formats tested: FP32, FP16, BF16, GF16, GF8, TF3, Ternary - Add GitHub Actions workflow for CI - Update build.zig with test-invariant step Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
