<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Structure preview errors with source-aware messaging/UI and enhance
local/Docker spawn error diagnostics and logging.
>
> - **Frontend**:
> - **Error model**: Change `previewErrorMessageAtom` from `string` to
`{ message, source }` to distinguish `preview-app` vs `dyad-app` errors.
> - **Preview UI**: Update `ErrorBanner` in
`components/preview_panel/PreviewIframe.tsx` to use `error.message`,
show an "Internal Dyad error" chip for `dyad-app`, conditional tip text,
and hide AI fix for non-`preview-app` errors; use `cn` helper.
> - **Error propagation**: Wrap iframe and build errors via
`setErrorMessage({ message, source: "preview-app" })`; adjust AI prompt
to use `errorMessage.message`.
> - **Hooks**:
> - `useRunApp`: On run/stop/restart failures, set `{ message, source:
"dyad-app" }` in `previewErrorMessageAtom`.
> - **Backend**:
> - `ipc/handlers/app_handlers.ts`: Improve spawn failure handling for
local node and Docker: capture stderr as strings, collect error details
(`message`, `code`, `errno`, `syscall`, `path`, `spawnargs`), log with
context, and throw enriched error messages.

Test cases:
- [x] create-ts-errors
- [x] with auto-fix
- [x] without auto-fix
- [x] create-unfixable-ts-errors
- [x] manually edit file & click recheck
- [x] fix all
- [x] delete and rename case
THINGS
- [x] error handling for checkProblems isn't working as expected
- [x] make sure it works for both default templates (add tests)
- [x] fix bad animation
- [x] change file context (prompt/files)
IF everything passes in Windows AND defensive try catch... then enable
by default
- [x] enable auto-fix by default
things to test:
- [x] allow real URL to open in new window
- [x] packaging in electron?
- [ ] does it work on windows?
- [x] make sure it works with older apps
- [x] what about cache / reuse? - maybe use a bigger range of ports??
