V43 Gate 1: Repair promoted canon predicates

Update historical V40 and V42 protocol predicates to accept the promoted V42 / draft V43 roadmap posture instead of requiring V41 active or a V42 working gate.

Add V42 to the protocol package boundary active/draft version table so the promoted canon pointer is accepted.

Proof: pnpm --filter @bitcode/protocol test; pnpm run check:v43-gate1; node scripts/check-bitcode-spec-family.mjs --version V43 --mode draft --current-target V42; node scripts/check-bitcode-canonical-inputs.mjs --current-target V42; node scripts/check-bitcode-canon-posture-drift.mjs --active-canon V42 --draft-target V43; git diff --check.
