Brandon Schneider 6c1d739a04 fix: correct Q16_16 add/sub signed/unsigned bug, add missing lemmas 
- FixedPoint.lean: rewrite add/sub with two's-complement overflow
  detection on UInt32 (replaces Int.ofNat approach that broke
  negative Q16_16 values). Both positive and negative inputs now
  correctly saturate at the representable bounds.
- FixedPoint.lean: add add_zero, zero_add, sub_self, sqrt_zero,
  sqrt_one theorems with proofs for the corrected add/sub.
- FixedPoint.lean: fix Q0_16 doc (0x7FFF = 1.0, not 0x8000)
  and div-by-zero (returns zero, not max).
- TorsionalPIST.lean: Fix16_sub_self, Fix16_mul_zero delegate to
  FixedPoint theorems; Fix16_add_zero proven via add_zero.
