The workflow worker fails to upload built logic function code to S3 when AWS returns a 503 SlowDown rate-limit error, causing workflow runs to fail. The S3 client has no custom retry configuration and the default 3-attempt retry with standard backoff is insufficient during request bursts.
Fix: packages/twenty-server/src/engine/core-modules/file-storage/drivers/s3.driver.ts
Add `maxAttempts: 5` and `retryMode: 'adaptive'` to both S3 client instantiations in the constructor (main client and presign client). The adaptive retry mode uses a client-side token bucket to dynamically reduce request rate when S3 returns 503 SlowDown responses, preventing cascading failures during high-concurrency worker bursts. The increased maxAttempts (from default 3 to 5) gives the adaptive backoff strategy sufficient headroom to succeed on transient rate limits.
Constructor: S3 client now created with `{ ...s3Options, region, endpoint, maxAttempts: 5, retryMode: 'adaptive' }` instead of `{ ...s3Options, region, endpoint }`. Same change applied to the presign client when presignEndpoint is provided.
