Prevents a Turbopack bug on Windows that caused the SWC worker to crash when reading external .js.map files in workspace-linked packages (paths were concatenated with mixed separators like 'packages/serde/dist\\index.js.map'). Once the worker crashed, the module graph entered a broken state where all subsequent requests returned 500, manifesting as flaky E2E Windows tests where the 'should rebuild on imported step dependency change' test would time out waiting for /api/workflows/start to succeed. Extends the original fix from #352 (previously applied only to @workflow/core and workflow) to the shared base tsconfig.json so that all packages producing a dist/ output benefit.

In monorepos the SWC transform seems to incorrectly translate the source map path that is embedded in the
corepackage's dist files and that causes a warning to be printed during build. Inlining the source maps fixes this. This seems like a band-aid solution to me and the real fix would be to address SWC's path resolving issue/configuration, but this could work as an interim solutionFixes#338.
