feat(turbopack): Log anonymized internal error (panic) information to telemetry (#81272) ## Goals - Pass through a custom `TurbopackInternalError` type when a Rust panic or an unexpected top-level `anyhow::Error` occurs. - Make a best-effort attempt to log a location of the error to telemetry. - In the case of a panic, we should have the file, line, and column where the panic occured. This could be obscured inside of a helper method, but it's better than nothing. Since this is a position in Turbopack's source code, there's zero risk of user data being included here, so it should be safe to log to telemetry. ## How it works In previous PRs, @wbinnssmith did the following: - Added a thread-local for storing the most recent panic information in Rust - Added `catch_unwind` logic to intercept the panic in turbo-tasks and read the thread-local information, with care take to make sure we're reading from the same thread (not across an `await` boundary). - Added a custom `std::error::Error` type for internal errors, with support for storing information about a source panic. - Ensured we set up `Error::source` correctly everywhere so that you can trace an error back to the root cause (presumably a panic). In #80881, I added a `NextTurbopackContext` type that we can extend to store additional helpers on. In this PR: - Adds a callback to the `Project` constructor called `throwTurbopackInternalError` that constructs and throws a custom `TurbopackInternalError`. The definition of `TurbopackInternalError` must be in JS, as we cannot reasonably define the error subclass using NAPI. - Wraps the callback in a `ThreadsafeFunction` so that it can be called in any of our async functions. - Replaces all the places we were previously converting to `napi::Error` with logic to run `throwTurbopackInternalError`. In a subsequent PR, we could move more of the panic handling into JS using `throwTurbopackInternalError`. ## Testing Added a panic and ran: ``` NEXT_TELEMETRY_DEBUG=1 pnpm next dev --turbopack examples/basic-css/ ``` <img src="https://graphite-user-uploaded-assets-prod.s3.amazonaws.com/HAZVitxRNnZz8QMiPn4a/7f261d3f-351e-436a-9345-fd6e9056d20c.png" width="600">
