Tool compatibility matrix and certification for external clients

[MPCoreDeveloper]

Summary

Create a formal compatibility matrix for external tools (DBeaver, Beekeeper Studio, DataGrip, pgAdmin, psql/libpq) with repeatable validation.

Why

Adoption depends on transparent compatibility guarantees.

Scope

• Define supported tool versions and drivers.
• Record supported workflows: connect, browse DB/tables, run query, introspect metadata.
• Capture known gaps and workarounds.
• Publish matrix in docs/server.

Implementation Plan

1. Define matrix template and pass/fail criteria.
2. Build repeatable smoke scripts for key workflows.
3. Execute validation against candidate tool versions.
4. Publish results and known limitations.

Acceptance Criteria

• Matrix published and linked from server docs/readme.
• At least 4 mainstream tools validated.
• Known limitations tracked as linked issues.

Dependencies

• Foundation issue for this epic.
