fix: force-replace npm's broken bin shims for pn/pnx aliases

Browse Source 
npm creates bin shims in .bin/ that point to an isolated copy in
.bin/.tools/. After self-update, setup.js fixes the main copy in
node_modules/@pnpm/exe/ but the .tools copy retains stale placeholder
files. Always replace the bin links so they point directly to the
fixed files instead of npm's broken .tools shims.
