Add: HarlonWang/eventbase

### Repository HarlonWang/eventbase ### Category Analytics ### What it replaces, in one sentence Mixpanel-style product analytics for mobile apps on D1: typed events, batched ingestion, a query API scripts and agents can call, with a Kotlin Multiplatform client. ### Anything else I maintain this project. It ships as an npm package (@whlong/eventbase) that you mount into your own Worker with Hono: the D1 schema, the ingestion endpoint and the query API all come with it, and there is no hosted service. The wrangler.toml in the repo is the vitest harness; in production the binding is your Worker's D1. Happy to add a standalone Worker if the list needs one.
