fix(docker): drop scripts/ from workspaces array (#4484)

`turbo prune sim --docker` strips `scripts/` from the pruned output (sim
doesn't depend on it), but the pruned root package.json still listed it
as a workspace, causing `bun install` to fail with "Workspace not found
'scripts'" in the Docker build.

scripts/ is dev-only tooling that runs from the repo root via `bun run
scripts/*.ts`. Its imports (glob, yaml) resolve against the root
node_modules — they're already in root devDependencies.

- Remove "scripts" from root workspaces array
- Delete scripts/package.json (no longer a workspace, manifest unused)
