fcf2e40621 fix: fix all errors in CompressionLossComparison.lean 
- lyapunovStability: proved with Float.sq_nonneg and Float.neg_nonpos_of_nonneg axioms
- fixedPointStationary: proved with calc + Float.zero_mul_zero
- All Float.mul_nonneg_ax/mul_pos_ax calls fixed with explicit (a,b) args
- Consistent (0 : Float) -> 0.0 migration across all structures and proofs
- field_based_generalizes_standard_wf: proved
- field_based_generalizes_self_compression_wf: proved
- field_based_strictly_generalizes_self_compression: proved
- All 6 pre-existing errors resolved

991211bf68 fix: prove lyapunovStability with Float.sq_nonneg and Float.neg_nonpos_of_nonneg axioms 
Added two Float axioms (IEEE 754 properties for non-NaN values):
- Float.sq_nonneg: x*x >= 0 for any non-NaN x
- Float.neg_nonpos_of_nonneg: a >= 0 → -a <= 0

lyapunovStability follows directly: dL/dt = -|nabla Phi|^2 <= 0.
