add jquick-sql to Database section

[paohaijiao]

Why this belongs in awesome-java

This project fills a distinct gap in the Java ecosystem:

• Unique value: Unlike traditional ORM tools or single-database connectors, jquick-sql provides a lightweight, embeddable federated query engine that can query across heterogeneous data sources (RDBMS, files, REST APIs) using standard SQL.
• Innovative approach: Implements a Coordinator-Worker architecture with optimizations including predicate pushdown, join reorder, and two-phase aggregation, making distributed query execution accessible with minimal overhead.
• Active maintenance: Project is actively maintained with regular updates and clear documentation.

Additional context

• License: Apache 2.0
• Project is open-source with clear contribution guidelines
• Demonstrates comprehensive SQL feature support including JOINs, subqueries, aggregations, and set operations (UNION/INTERSECT/MINUS)

<violation number="1" location="README.md:504">
P1: This project addition is made to the wrong file. README.md is generated from README_SOURCE.md (see the header comment and the GenerateReadme.java pipeline), and the repository's CI explicitly rejects direct README.md edits: the 'Reject direct README changes' step in .github/workflows/update-readme.yml fails the build with 'README.md is generated. Edit README_SOURCE.md instead.' when README.md is touched. Because the entry exists only in README.md and not in README_SOURCE.md, it also disappears the next time the README is regenerated, so the listing never actually ships. Move the JQuick SQL entry into the Database section of README_SOURCE.md (alongside the other DB entries, e.g. after Flyway) in the required `- [Name](URL) - description` format, and leave README.md untouched.</violation>
