feat(wave): non-vacuous chiral spinor charge path (ADR-0241 P8)

- Implemented design (A) for P8: odd-capable mixed-parity spinor packets
  produce a strictly non-vacuous and informative chiral charge
  Q = <ψ I_5 ~ψ>_0 that measures correlation between the even and odd-dual parts.
- Proved via TDD that Q is non-vacuous on mixed-parity spinors and strictly
  conserved under left unitary rotor multiplication.
- Updated wave_manifold.py docstrings to clarify that while Q is structurally
  vacuous for even field-states (retiring #19), it is fully functional for
  general spinors.
- Flipped W4 in the fidelity scorecard to GREEN and updated ADR-0241.
