Version: scriptc 0.4.11, main at 918d80b.

Repro:

// dyn.ts
const m = await import("ms");
console.log(m.default(1000));

scriptc build dyn.ts where no static import names ms.

Actual: the SC2013 refusal names @types/ms (the resolved declaration package) instead of ms, and gives no way forward.

Expected: the diagnostic names the package the user wrote, and hints at the fix: add a static import so the package joins the module graph, or allow a Node island.

Changes: a shared runtimePackageName strips the @types/ scoping, unsupportedPackageImportDiag takes an optional hint, and the lazy import lowering passes it. Test added in tests/harness/lazy-package-import.test.ts; the lazy-import, diagnostics and lower-stdlib suites pass locally (37 tests). pnpm lint could not run in my environment (ESLint JSON parse failure); oxlint and format:check are clean.

Whether literal import("pkg") should follow into the module graph is a separate question, filed as an issue.
