Show HN: Bunqueue – Saga workflow engine for Bun with embedded SQLite

Orchestrate multi-step workflows with saga compensation, step retry, parallel execution, conditional branching, nested sub-workflows, human-in-the-loop signals with timeout, loops (doUntil/doWhile), forEach iteration, map transforms, schema validation, per-execution subscribe, observability events, and cleanup/archival. Zero infrastructure — no Redis, no Temporal, no cloud service. TypeScript DSL built on bunqueue.
