feat(elreal): non-finite state + conversion/logic/arithmetic suites (#1079 Phase 5) (#1084)

Final phase of the elreal class facade (#1079). class elreal gains a dedicated
IEEE-style non-finite classification (elreal_class finite/pinf/ninf/qnan + _cls).

- operator=(double) classifies NaN/+-Inf; propagates by IEEE-754 through arithmetic
  (inf+finite=inf, inf-inf=nan, inf*0=nan, x/0=+-inf, 0/0=nan, finite/inf=0, nan
  propagates), comparison (elreal_order_of: NaN unordered, -inf<finite<+inf),
  conversion, unary minus, abs. New isnan/isinf/isfinite; sign/scale/iszero are
  non-finite-aware. elreal_cmp stays the finite (depth-bounded) primitive.
- numeric_limits: has_infinity/has_quiet_NaN now true; infinity()/quiet_NaN()
  return the real states (is_iec559 false; snan folds to qnan).
- attributes: free isnan/isinf/isfinite/signbit. manipulators render nan/+-inf
  (to_triple uses an unsigned tag since the sign is a separate field).
- Suites: conversion/, logic/, arithmetic/class_arithmetic (class-level, incl the
  IEEE non-finite table); el_conversion/el_logic CMake targets.

Full elreal ctest 42/42 gcc + clang; gcc Debug-with-assertions green; full CI
(11 platforms + ASan/UBSan/Coverage/Clang-Tidy) green. Completes epic #1079.
