Development record

The package runners beside npx, npm exec, pnpm dlx and yarn dlx are not read as wrappers, so a blocker behind them only warns as an unrecognised launcher: pnpm exec, yarn <pkg>, yarn exec, bunx, bun x and pnpx each run the program their first operand names, and pnpm exec kill-port 3000 or bunx kill-port 3000 warns where npx kill-port 3000 blocks.
