Fixes local `npm install` failures on the build machine:
- @jsr:registry=https://npm.jsr.io — the Nostrify stack depends on JSR packages
(@jsr/std__encoding, etc.) that don't exist on registry.npmjs.org; without
this mapping npm 404s. The lockfile already resolves them via npm.jsr.io, but
a fresh install from package.json needs the scope registry configured.
- legacy-peer-deps=true — resolves the long-standing benign peer-range lags
(e.g. react-day-picker@8 peers date-fns 2/3 while the app uses date-fns 4)
the same way the hosted build environment does, instead of ERESOLVE.
