Turbopack panics: create discussions with pre-filled errors (#76850)
This:
- Prompts users to report turbopack internal errors as new GitHub
discussions instead of issues
- Encodes the error message and debug information into the discussion
title and body respectively
- Since these encoded urls can be lengthy, it uses [Terminal
Hyperlinks](https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda)
to present things concisely without excessive wrapping. If the terminal
does not support this, only the error message is sent.
- Removes specific panic handling in favor of the `subscribe` napi error
handler. This seems to be the vast majority of panics.
Test Plan:
In a terminal with hyperlink support `FORCE_HYPERLINK=1 pnpm next dev
--turbo examples/basic-css/`:
```
