Confidence Score: 5/5 - Safe to Merge

Safe to merge — this PR makes a single, isolated documentation change to README.md by adding a DeepWiki badge with no impact on runtime behavior, logic, or security. The badge is correctly formatted as a markdown image link pointing to https://deepwiki.com/mindsdb/mindsdb, which is a legitimate external documentation discovery service. No review comments were generated and no existing unresolved issues exist in this changeset.

Key Findings:

• The change is purely additive to README.md — a single badge insertion with no modifications to existing content, code, or configuration files.
• The DeepWiki badge URL and image link follow standard markdown badge conventions consistent with the existing badge styling in the README.
• Zero runtime, logic, security, or performance implications exist since this is a static documentation file change only.
