Brummel e37366f8dd spec: floats LLVM-IR fixes — fcmp une for !=, synth.rs sites, container-slot precision 
Three classes of fix from the LLVM-IR audit:

1. != on Float: fcmp une, NOT fcmp one. one is 'ordered and not
   equal' (false for nan!=nan, breaks IEEE / user-fixed constraint).
   une is 'unordered or not equal' (true for nan!=nan, matches IEEE
   and Rust f64::ne).

2. crates/ailang-codegen/src/synth.rs touches the Float primitive at
   five sites the original spec missed: llvm_type, builtin_ail_type,
   builtin_effect_op_ret, type_descriptor (descriptor 'Fl' to avoid
   collision with ADT-name F-prefix), builtin_binop (becomes a
   transitional artefact, replaced by type-dispatched helper).

3. Float literals lower as LLVM hex-float syntax (double 0x4014...);
   nan/inf/neg_inf as direct SSA double constants at use site (NOT
   via the __unreachable__ analogue, which is a terminator
   instruction not a value); container slot layout precision
   (monomorphisation vs bitcast).

Brummel f7e2c3ee7a spec: floats — operators polymorphic over {Int, Float} + NaN/Inf constants + is_nan 
Mainstream-aligns the Float surface: + - * / < <= > >= become
forall-quantified with codegen-dispatch on Int|Float (parallel to
today's == path), instead of the original draft's wort-style
fadd/flt/etc. Adds nan/inf/neg_inf as builtin constants and
is_nan : (Float) -> Bool. % stays Int-only (no fmod yet).

Iteration plan now flags iter 3 and iter 4 as widening passes
that must hold the no-Int-regression line.
