fix(cli): add typescript devDep to fix typecheck for bundler moduleResolution

backend-only and discussions were missing typescript as a
devDependency, causing npx tsc to fall back to the root
tsc v4.9.5 which doesn't support moduleResolution:"bundler".
Also restores monorepo metadata in discussions snapshot
package.json files.
