The first public release of Lakefront, an HTAP engine for TypeScript on Bun.

- `open()` an engine against a Postgres catalog and a data directory; boards are created on first write, with columns inferred or declared up front.
- Writes are durable at the Postgres commit through a group-committed write-ahead log, and are flushed into a DuckLake of Parquet files off the write path.
- Reads come from per-board DuckDB replicas, with read-your-write watermarks.
- `watch()` gives one change feed, identical embedded and over HTTP.
- `serve()`, `route()` and `connect()` run it as HTTP server nodes behind cache-affinity routing, with a typed client and capability tokens.

Requires Bun 1.2 or later. Docs: https://lakefront.folsomintelligence.com
