didericis f54b66f857 Add double-contraction reductio strategy note ...

Records the degree-5 double-contraction proof skeleton: Kempe chains as
Heawood face-chains (flip-set + same-side sign rule), the chain-transport
hypothesis L1, the inner/outer nested reductio, H'' as per-interface
contraction along the chain, and the single emptiness Claim it reduces to,
with the Errera oracle as the stress test.
