feat(cli): add elide db studio command

[franklinfollis]

Summary

This PR adds the command db studio, which launches a web-based database management UI that runs entirely on the Elide runtime. It provides a modern interface for viewing and editing databases with support for CRUD operations, schema management, and SQL queries. For now, it only works with SQLite, via Elide's SQLite bindings.

Usage

# Automatic discovery - finds all [.db|.db3|.sqlite|.sqlite3] files in current and immediate directories
elide db studio

# Specific directory
elide db studio path/to/my/databases/

# Specific database
elide db studio path/to/database.db

# Opens browser to http://localhost:8080 with UI

What it does:

• Extracts all necessary files under .dev/db-studio/ on first run.
• Launches two servers:
  • API server (port 4984): TypeScript REST API using elide:sqlite
  • UI server (port 8080): React frontend served as static files

Architecture

• Backend: TypeScript REST API with custom HTTP routing, Zod validation, and SQLite integration via elide:sqlite
• Frontend: React 19 app built with Vite, shadcn/ui, TailwindCSS 4, and TanStack Query for data management
• Configuration: Ports and database paths configured via elide.pkl manifests or via CLI args

Directory structure:

.dev/db-studio/
├── api/          # TypeScript API
└── ui/           # Statically built React app

Features

Drizzle Studio was the main inspiration behind many of the operations, including:

• Query editor/SQL Console to run directly against the database
• Simple filtering of rows and columns, and sorting when viewing tables
• Adding, deleting, and editing data directly in tables
• Creating, dropping, and truncating tables

Future Plans

• Create a db file through the UI (at the moment db files need to already exist)
• Data export (CSV/JSON)
• PostgreSQL/MySQL support

initial comments, otherwise i'll try it and see if we can get this into 1.0.0-beta11 🥳

absolute symlink? or what's up with this

[sgammon]

files will need copyright header; IDEA will apply it for you automatically, can help configure it in discord

[sgammon]

should dist assets be committed to source control?
