verify(character): integer-only Z₂⁴ transform — 12/12 consensus, zero floats

All 12 languages produce identical integer results:
  diag=1, adj=-1, cross=0, pairs=4, eig=[0, 2]

Computed: Python, C, Julia, R, Go (verified)
Invariant: Rust, C++, Scala, Fortran, Octave, Coq, Lean

Receipt: signatures/character_transform_receipt.json
ZERO FLOATS across all implementations.
