Self-hosted instances on the R2/S3 backend could only upload a video as a single PUT, which fails behind a Cloudflare proxy/tunnel (100MB request-body cap) and is capped at 5GiB with no resilience. Bunny already avoids this via tus; this brings the R2/S3 path to parity. Files larger than a threshold (default 90MiB) are now split into parts (default 32MiB, min 5MiB) and uploaded directly browser->R2 via presigned UploadPart URLs, then reassembled server-side with CompleteMultipartUpload. Each request stays under the 100MB cap, lifts the size ceiling well past 5GiB, and adds per-chunk retry. Files at/under the threshold keep the existing single-PUT path unchanged. Bunny path is untouched. Thresholds are env-overridable via OPENFRAME_R2_MULTIPART_THRESHOLD_BYTES and OPENFRAME_R2_MULTIPART_PART_SIZE_BYTES. Verified end-to-end against real Cloudflare R2 and a local MinIO behind an nginx 90MB cap (single 141MB PUT 413s on master; 32MB parts pass here). Closes #22
