feat: Enhance error fallback with source maps (#932)

* feat: Enhance error fallback with source maps

Enhance the `ErrorFallback` component to automatically attempt
to decode minified stack traces using available source maps.

This significantly aids debugging production errors by:
*   Resolving file paths, line, and column numbers to original
    source locations.
*   Introducing a recursive display for error causes (`error.cause`).

This functionality is implemented via the new `useReadableStack`
hook and the `source-map-js` dependency.

* Update src/components/ErrorFallback.tsx

* fix: Log error on stack decode failure

Improves error handling in the stack trace decoding hook.

If `decodeStackTrace` fails, the error is now explicitly logged
to the console, aiding debugging when stack decoding processes
are interrupted.

Also updates promise consumption to use `void` and removes
outdated eslint suppression comments.

* refactor: Type source map cache explicitly

This commit introduces the `RawSourceMap` type definition from
`source-map-js`.

The source map cache and the subsequent use of source map data
are now explicitly typed, improving type safety when interacting
with `SourceMapConsumer`.
