v0.3.0

v0.3.0 — Export Decorators + Storage Drivers

Export Decorators

• @Exportable() — Class decorator to mark entities/DTOs as exportable with optional title, auto-filter, auto-size, frozen rows/columns, and column widths
• @ExportColumn() — Property decorator to configure column order, header, format, width, and value mapping
• @ExportIgnore() — Property decorator to exclude a property from the export
• buildExportFromEntity() — Reads decorator metadata and builds a concern-compatible export object
• ExcelService — New entity-based methods: downloadFromEntity(), downloadFromEntityAsStream(), storeFromEntity(), rawFromEntity()
• Full inheritance support: child classes inherit, override, or ignore parent columns

Storage Drivers

• StorageDriver — Pluggable interface with put(), get(), delete(), exists() methods
• LocalDriver — Local filesystem storage (default, zero-config)
• S3Driver — AWS S3 and S3-compatible services (MinIO, R2, DigitalOcean Spaces)
• GCSDriver — Google Cloud Storage
• AzureDriver — Azure Blob Storage
• DiskManager — Injectable service to manage named storage backends with lazy instantiation and caching
• store(), storeFromEntity(), import(), toArray(), toCollection() now accept an optional disk parameter
• Three credential strategies: SDK default chains, inline config, pre-configured client injection
• All cloud SDKs are optional peer dependencies — only install what you use
