Adds chdb to the Database section.
chdb is an in-process OLAP SQL engine that embeds the full ClickHouse
query engine in Python. It runs the complete ClickHouse SQL dialect
(1000+ functions), queries Parquet/CSV/JSON files in place, references
pandas DataFrames directly in SQL with zero-copy, and federates to remote
ClickHouse clusters via `remoteSecure()`.
Acceptance criteria: Hidden Gem — chdb solves the niche of running the
ClickHouse SQL surface in-process in Python. Demonstrated real-world
usage includes Hex's first-class integration and inclusion in ClickBench.
The repository is 3+ years old with a multi-language binding ecosystem
(Python / Bun / Go / Rust / Ruby / Zig / Java / .NET).
