feat(elreal): numeric_limits + attributes + manipulators (#1079 Phase 3) (#1082)

Phase 3 of the elreal class facade (#1079): the standard query/render surface.

- numeric_limits<elreal<FpType>>: precision-parametrised, finite-only
  (non-finite predicates false, factories return 0), is_bounded=false
  (unbounded integer<256> exponent); denorm_min()==min() per the denorm_absent
  contract; precision fields against the nominal default precision.
- attributes.hpp: sign / scale (int64_t, no exponent narrowing) / significand.
- manipulators.hpp: type_tag, to_components, to_binary, to_triple (emits the
  significand in [1,2)), operator<< / operator>>.
- elreal_impl.hpp: kElrealDefaultPrecision constant; sign()/scale()/isneg();
  std::accumulate / std::find_if in approx and elreal_cmp.

Test: elastic/elreal/api/math? -> api/attributes.cpp (numeric_limits, attributes,
manipulators). gcc + clang + gcc Debug-with-assertions green; CodeRabbit findings
resolved and confirmed.
