v5.3.0

Chat2DB Community 5.3.0 is a major new baseline for the Community edition and a fresh start for regular releases and ongoing maintenance.

## Highlights

- **Unified versioning:** Community moves from the separate `0.3.x` line to `5.3.0`, aligned with the current Chat2DB product family.
- **Shared database client core:** Community, Pro, and Enterprise now share the same database client foundation, with the public Community repository serving as the upstream for that shared core.
- **Local-first experience:** No registration or sign-in is required. Data sources, query history, tasks, dashboards, and AI configuration are stored locally on your device.
- **Complete database workflow:** Connect to data sources, browse metadata, edit and execute SQL, manage database objects and data, import and export data, save SQL and history, and build dashboards and charts.
- **Extensible tooling:** Use the Chat2DB CLI, MCP integration, and your own configured AI models.
