Just Enough Backups (JEB)

Added

• S3-compatible and WebDAV backup storage with bounded streaming uploads, published catalogs, checksums, and remote retention.
• Dedicated "Remote" tab in the in-game configuration screen with provider selection (S3 / WebDAV), connection settings, retry options, and masked credential fields.
• Support for large S3 backups via multipart copy and 5GB partition handling.
• Zstandard compression (ZSTANDARD) for ZIP entries with configurable level (zstdCompressionLevel, 1–22) and parallel multi-threaded compression support; existing DEFLATED backups remain readable.
• Parallel multi-threaded compression for both DEFLATED and ZSTANDARD modes, with scratch file spilling for large Zstandard entries to bound memory usage.
• Configurable Deflate compression level (deflateCompressionLevel, 1–9) for standard DEFLATED backups.
• Configurable per-type minimum age for startup backups (startupBackupThreshold for FULL, DIFFERENTIAL, and PARTIAL). A value of 0 preserves the previous behavior.
• Support for setting remote credentials via environment variables (JEB_S3_ACCESS_KEY_ID, JEB_S3_SECRET_ACCESS_KEY, JEB_WEBDAV_USERNAME, JEB_WEBDAV_PASSWORD) or server config file.

Fixed

• Reduced distributed mod JAR size from ~18MB to ~10MB by pruning unused architecture native binaries in zstd-jni (retaining standard 64-bit platforms: Windows x64, Linux x64, macOS ARM64/x64) and aligning Netty/Commons dependencies with Minecraft runtime.
• Input fields in configuration and backup management screens now properly lose focus when clicking outside.
• Pressing ESC in the backup management screen now properly closes modal confirmation dialogs (restore and delete modals).
• Prevented integer overflow in progress percentage calculation for backups larger than 2GB.
• Fixed WebDAV remote storage streaming, collection paths, and redirect handling.
