Greptile Summary

This PR implements a targeted fix for a compatibility issue between Next.js 15.5.0 and Bun's CommonJS module bundling system. The changes downgrade Next.js from version 15.5.0 to ^15.3.2 and adjust source map configuration to work around Bun issue #21137.

The fix involves two key modifications:

1. Package downgrade: Next.js is reverted from 15.5.0 to ^15.3.2 in package.json, allowing patch updates within the stable 15.3.x series while avoiding the problematic version
2. Source map configuration adjustment: The next.config.ts file removes the general productionBrowserSourceMaps: false setting and adds turbopackSourceMaps: false to the experimental section, indicating a shift to Turbopack-specific source map control

This approach maintains the project's Bun-centric architecture (evident from the oven/bun:alpine Docker base image and bun engine requirements) while ensuring build stability. The solution is temporary, designed to maintain functionality until the upstream Bun issue is resolved, at which point Next.js can be upgraded again.

Confidence score: 5/5
