* 🪣 fix: S3 path-style URL support for MinIO, R2, and custom endpoints
`extractKeyFromS3Url` now uses `AWS_BUCKET_NAME` to automatically detect and
strip the bucket prefix from path-style URLs, fixing `NoSuchKey` errors on URL
refresh for any S3-compatible provider using a custom endpoint (MinIO, Cloudflare
R2, Hetzner, Backblaze B2, etc.). No additional configuration required — the
bucket name is already a required env var for S3 to function.
`initializeS3` now passes `forcePathStyle: true` to the S3Client constructor
when `AWS_FORCE_PATH_STYLE=true` is set. Required for providers whose SSL
certificates do not support virtual-hosted-style bucket subdomains (e.g. Hetzner
Object Storage), which previously caused 401 / SignatureDoesNotMatch on upload.
Additional fixes:
- Suppress error log noise in `extractKeyFromS3Url` catch path: plain S3 keys
no longer log as errors, only inputs that start with http(s):// do
- Fix test env var ordering so module-level constants pick up `AWS_BUCKET_NAME`
and `S3_URL_EXPIRY_SECONDS` correctly before the module is required
- Add missing `deleteRagFile` mock and assertion in `deleteFileFromS3` tests
- Add `AWS_BUCKET_NAME` cleanup to `afterEach` to prevent cross-test pollution
- Add `initializeS3` unit tests covering endpoint, forcePathStyle, credentials,
singleton, and IRSA code paths
- Document `AWS_FORCE_PATH_STYLE` in `.env.example`, `dotenv.mdx`, and `s3.mdx`
* 🪣 fix: Enhance S3 URL key extraction for custom endpoints
Updated `extractKeyFromS3Url` to support precise key extraction when using custom endpoints with path-style URLs. The logic now accounts for the `AWS_ENDPOINT_URL` and `AWS_FORCE_PATH_STYLE` environment variables, ensuring correct key handling for various S3-compatible providers.
Added unit tests to verify the new functionality, including scenarios for endpoints with base paths. This improves compatibility and reduces potential errors when interacting with S3-like services.
