## Description This PR adds two read-only, PostgreSQL tool kinds to MCPToolbox that standardize discovery of extensions: - `postgres-list-installed-extensions` – lists extensions installed in the current database with: `name`, `version`, `schema`, `owner` `description`. - `postgres-list-available-extensions` – lists extensions available to install on the cluster with: `name`, `default_version`, `description`. Both are safe by default, and return well-typed JSON suitable for UIs, agents, and automation. **Test Output** - `list_installed_extensions` <img width="1414" height="781" alt="image" src="https://github.com/user-attachments/assets/aab102a7-90ab-4516-9bc2-bcbfdab02bb1" /> - `list_available_extensions` <img width="1421" height="774" alt="image" src="https://github.com/user-attachments/assets/a4f80f22-bb2e-4350-acb2-12eb020d88cb" /> --- > Should include a concise description of the changes (bug or feature), it's > impact, along with a summary of the solution ## PR Checklist --- > Thank you for opening a Pull Request!
