chore(deps): drop @typescript/native-preview in favor of typescript 7 native tsc

TypeScript 7's own tsc is the Go-native compiler, so the separate tsgo
binary from the dev-preview package is redundant. yarn type-check now
runs tsc --noEmit. Bump tsconfig target to ES2018 and add types: [node]
to fix the pre-existing NodeJS namespace, global, and /s regex flag
errors that stable tsc reports but tsgo did not.
