test(runtime): full wrap-mode transition matrix; vouch the wrap re-measure divergence (#200)

Encode the declarative invariant for the runtime `wrap` re-measure fix
(PR #193) as a full matrix: for all 6 wrap modes and all 30 ordered
transitions, toggling `wrap` at runtime produces the exact same frame as
a fresh mount with that wrap (measure == paint). Ground-truth fresh-mount
frames are derived at runtime, not hardcoded. Reverting the one-line fix
in node-ops.ts turns 16 of the 30 transitions red, so the matrix
genuinely guards the fix.

Vouch the divergence: add [VOUCHED @hyf0] to the ink-divergences.md entry
and reword it to lead with correctness (Ink v7.0.4 has the latent stale
measure bug; vue-tui keeps the correct invariant). Drop "pending a human
vouch" from the node-ops comment.
