feat(ucalc): decimal float steps visualization (#678)

* feat(ucalc): decimal float steps visualization (#655)

Add dfloat-specific step-by-step arithmetic decomposition showing:
1. Decompose: sign, decimal coefficient, decimal exponent
2. Align decimal exponents (scale up the larger-exponent operand)
3. Add/subtract decimal coefficients (integer arithmetic)
4. Normalize: ensure ndigits significant digits
5. Result

Educational value: 0.1 + 0.2 = 0.3 is exact in decimal float
(coefficients 1 + 2 = 3), contrasting with binary float where
0.1 + 0.2 = 0.300000012 due to binary representation error.

Detects dfloat types by type_tag prefix. Extracts ndigits from tag.

Resolves #655

* fix(ucalc): resolve CodeRabbit review items for dfloat steps

Four fixes:

1. Critical: coefficient arithmetic uses double instead of long long
   to avoid overflow for decimal64 (10^16 * 10^16 exceeds int64).

2. Post-round carry normalization: shared normalize_coefficient()
   handles carry from rounding (e.g., 99995 -> 10000).

3. Division explainer added: explain_dfloat_div shows scaled
   coefficient division with ndigits precision.

4. Header comment documents double-based decomposition limitation.
