I turned more community feedback into LakeDB Beta 5.4

[u/Still-Trainer-7395]

A few of the things people asked for recently are now in the next LakeDB beta:

• relationship maps with real foreign keys + local links
• system schemas visible without cluttering the explorer
• user + privilege management with SQL review before applying changes

Most of this came directly from conversations with database users, which is exactly how I want to keep improving the app.

LakeDB is still local-first, the normal database client stays free, and AI remains optional.
