V30: Fix wrapped demonstration promotion posture

Broaden the runtime promotion README rewrite so it handles the real demonstration paragraph when the generated appendix path is wrapped onto the next line.

Proof: npm --prefix protocol-demonstration run test:v22-canon-drift; node scripts/check-bitcode-canon-posture-drift.mjs --active-canon V29 --draft-target V30; copied promotion repro with V30/V31 drift check.
