[Feature Request]: Logical Database Aliases and Metadata (Description, Tags)

Problem

Logical databases (db0, db1, ...) are only shown by numeric index. In real projects each index serves a different purpose (sessions, cache, queues, etc.), but there's no way to tell which is which without digging through docs or code.

Proposal

Let users assign an alias, short description, and optional tags to each logical database (via UI and/or a shareable config file, e.g. redis-db-map.json).

Instead of manually typing/selecting the DB by index, show a dropdown/list of logical databases (by alias) when switching databases.

Example

DB	Alias	Description	Tags
db0	Sessions	User sessions & tokens	auth, session
db1	Cache	Application cache	cache
db2	Queues	Background job queues	queue, jobs
db3	Rate Limit	Request rate limiting	rate-limit

Benefits

• Faster onboarding, fewer mistakes (wrong DB selected)
• Self-documenting database browser
• Config file can be shared/versioned across the team
