๐ Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a ๐ emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

Inline comments:
In `@src/export/gherkin.ts`:
- Around line 43-47: The current check uses resolve/relative and isAbsolute on
outputPath but does not resolve symlinks, so an attacker can escape the project
root via symlinked directories; update the validation around outputPath (the
computed outputPath and rel variables used before throwing VspecError) to
compare real filesystem paths: obtain real paths for config.root and the
output's nearest existing ancestor (using fs.realpathSync or async fs.realpath)
and ensure the real output path starts with the real root, or alternatively walk
path segments of outputPath and lstatSync each segment to reject any symlinked
component before calling mkdirSync(dirname(outputPath)) or
writeFileSync(outputPath,...). Ensure the same checks are applied wherever
outputPath is created/used.
