BlazorMemory v0.3.0 Adds Export and Import for Browser‑Based Memories

Storing memories in the browser is fragile—clearing data or switching devices wipes everything—so BlazorMemory v0.3.0 introduces ExportAsync and ImportAsync to serialize and restore user memories in JSON. ExportAsync returns a JSON payload that includes userId, exportedAt, version, and an array of memories with id, content, and learnedAt, but deliberately omits embeddings to keep file size small and avoid model coupling. ImportAsync reads the JSON, skips any memory whose content already exists to avoid duplicates, and regenerates embeddings on import, ensuring compatibility across different embedding providers. The MemoryPanel component now includes Export and Import buttons in its footer, which trigger a browser file download and a file picker that accepts .json files, respectively. These buttons can be hidden via AllowExport and AllowImport parameters. The component is part of the BlazorMemory.Components package and requires the BlazorMemory.Storage.IndexedDb, BlazorMemory.Embeddings.OpenAi, and BlazorMemory.Extractor.OpenAi packages. The implementation uses dotnet add package commands to pull the necessary NuGet packages and a builder.Services.AddBlazorMemory() configuration that sets up IndexedDb storage and OpenAI embeddings. The export/import flow is fully functional out of the box, allowing developers to add persistence to their memory‑based applications without writing custom code.
