chore(orchestrator): fix pre-existing Prettier drift in README.md

Whitespace-only markdown table/spacing fix. Pre-existing on origin/main
(introduced by #868), unrelated to #869 C1 — fixed only because the repo's
pre-push hook runs a full-repo \`pnpm format:check\` and was blocking this
branch's push. No functional change.
