⚡ Bolt: [performance improvement] Optimize dashboard projects health endpoint

[bobdivx]

💡 What: Initiated external ZimaOS fetch as an un-awaited Promise and used Promise array mapping for sequential file IO.

🎯 Why: Sequential awaits for slow network fetches and filesystem disk lookups were bottlenecking Astro API route response times.

📊 Impact: Transforms O(n) blocking sequential filesystem checks into concurrent O(1) checks, and overlaps external payload fetching with local queries, massively reducing TTFB.

🔬 Measurement: Confirmed unit and functional tests still pass with correct fallback behavior handling.

Code Review

This pull request optimizes the performance of the dashboard-projects-health API route by parallelizing external network requests and concurrently initiating project status checks. While these concurrency optimizations are beneficial, the current implementation swallows errors during the concurrent execution of project status checks, which breaks the original error handling inside the loop. It is recommended to capture these errors and throw them when awaiting the promises to preserve the correct error behavior.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

By catching errors inside the map function and returning { resolved: null, st: null }, the promise rejection is swallowed. This prevents the try/catch block inside the loop from catching any filesystem or database errors, meaning the error handler will never execute and the user will see a generic 'Chemin projet introuvable...' hint instead of 'Erreur lecture disque'. To preserve the original error handling behavior while avoiding unhandled promise rejections, capture the error in the promise chain and throw it when awaiting the promise.

Check if an error was captured during the concurrent execution of the promise, and throw it to ensure it is caught by the surrounding try/catch block.

        const res = await resolvedPromise;
        if (res.error) {
          throw res.error;
        }
        const resolved = res.resolved;
        const st = res.st;
        if (resolved) {
