Cloudflare R2

Added

• Added presigned upload support, letting clients upload straight to the bucket instead of proxying the bytes through PHP
• Added presigned support for replacing an existing asset's file, including transform invalidation and the beforeReplaceFile/afterReplaceFile events
• Added a “Use Presigned URLs” filesystem setting, off by default, with a configurable size threshold below which uploads keep going through PHP
• Added a progress readout for direct uploads whose caller doesn’t already show one, so replacing a file no longer sits on a bare spinner
• Added a warning when navigating away from an in-progress direct upload, and a best-effort abort so abandoned multipart uploads stop costing storage
• Added SupportsPresignedUploads, which Fs now implements
• Added Fs::isPresignedUploadEnabled(), Fs::getPresignedUploadThreshold(), and Fs::shouldPresignUpload() so consumers can ask the filesystem rather than hardcoding the policy
• Added Fs::getPresignedUpload() for single-request uploads
• Added Fs::beginMultipartUpload(), Fs::getPresignedUploadParts(), Fs::completeMultipartUpload(), and Fs::abortMultipartUpload() for multipart uploads
• Added Fs::getMultipartPartSize(), which returns a uniform part size, as R2 requires of all but the final part. Sizes scale with the file to keep the part count sane — a 626 MB upload is 40 parts, not 126
• Added Fs::getUploadedParts(), so callers can ask the bucket which parts arrived instead of relying on the client reading ETag response headers
• Added PresignedUpload, PresignedUploadPart, and MultipartUpload models

• Update variables/classes to avoid conflicts with S3 plugin
