IndexedDB ORM

A promise-based ORM wrapper for IndexedDB, providing a fluent query builder with support for model instances, relationships (hasOne, hasMany), indexing, aggregations, and transactional actions. Current stable version 2.1.0 (legacy branch) while v4.0.0-alpha.3 is under development. Key differentiator is a full ORM layer with relations and custom classes, unlike simpler wrappers like Dexie.js which focus on queries. Ships TypeScript types. Note: v4.0.0-alpha is unstable and has breaking changes from v2.1.0.
