Closes #678

Changes Made

• Updated the root page meta description in src/app/layout.tsx.
• Replaced the outdated list of specific database engines with a broader SQL and NoSQL description.
• Updated the description to better reflect the database management, schema exploration, query, data import, and AI-assisted capabilities.

Testing

• git diff --check` passed

• bun run test completed, but the full test suite had unrelated existing failures (478 failed, 6 errors)

• I have tested this locally

• I have added/updated tests

• All existing tests pass

Test Environment

• LibreDB Studio Version: Development build
• Browser: Google Chrome
• OS: Windows
• Node.js/Bun Version: Node.js v24.14.0 / Bun 1.4.2
• Database Type: NA-metadata-change only
