Include scripts in typecheck (#2928)

The `scripts/` directory was excluded from type checking entirely.
Add a dedicated `scripts/tsconfig.json` and run it as part of `npm run typecheck`.
Also add `scripts/**/*` to the root `tsconfig.json` for IDE coverage.

A root `tsconfig.json` change alone would not make `npm run typecheck`
validate `scripts/`.
The previous root `typecheck` command only ran workspace checks, and
`scripts/` is not a workspace.
Using the root `tsconfig.json` directly for CI is also not viable yet
because it still surfaces pre-existing `import.meta` errors from
`apps/cli`, which has its own tsconfig with the correct module settings.

This means the dedicated `scripts/tsconfig.json` and the `package.json`
update are the functional part of the fix, while the root
`tsconfig.json` include improves IDE coverage.
