Adds a new 'S3-Compatible Storage' provider that works with any
S3-API-compatible object storage service, including MinIO, Ceph,
Cloudflare R2, Backblaze B2, and others.
Changes:
- New provider class: classes/providers/storage/s3-compatible-provider.php
- Provider key: s3compatible
- Reads user-configured endpoint URL from settings
- Uses path-style URL access (required by most S3-compatible services)
- Supports credentials via AS3CF_S3COMPAT_ACCESS_KEY_ID /
AS3CF_S3COMPAT_SECRET_ACCESS_KEY wp-config.php constants
- Disables AWS-specific features (Block Public Access, Object Ownership)
- New provider SVG icons (s3compatible.svg, -link.svg, -round.svg)
- Registered provider in main plugin class with endpoint setting support
- Updated StorageProviderSubPage to show endpoint URL input for S3-compatible
- Built pro settings bundle with rollup (Svelte 4.2.19)
- Added package.json and updated rollup.config.mjs for pro-only builds
