Add Docker support with pre-installed apps

[shashankanil]

Adds Docker deployment support for OpenUI with two modes: Full mode (everything containerized) and Hybrid mode (UI in container, agents on host).

Changes
Dockerfile
Multi-stage build with Alpine (builder) and Debian (production)
Uses oven/bun:1.3-debian for glibc compatibility with bun-pty
Pre-installs AI tools:
Claude Code (@anthropic-ai/claude-code)
OpenCode (opencode-ai)
Ralph (autonomous loop from frankbria/ralph-claude-code)
Node.js 22 via NodeSource for npm package support
Health check endpoint at /api/config
docker-compose.full.yml
Complete containerized deployment
Mounts project directories and git credentials
Resource limits (4 CPU, 4GB RAM)
Persistent volumes for state and plugin data
docker-compose.hybrid.yml
UI in container with host networking (Linux only)
Mounts host-installed AI tools
Docker socket access for host process spawning
Designed for environments where agents should run natively
Usage
bash

Full mode (recommended)

docker compose -f docker-compose.full.yml up -d

Hybrid mode (Linux only)

ANTHROPIC_API_KEY=your-key docker compose -f docker-compose.hybrid.yml up -d
Access at: http://localhost:6968

Notes
Hybrid mode uses network_mode: host which only works on Linux, not macOS/Windows Docker Desktop
ANTHROPIC_API_KEY environment variable required for Claude Code functionality
