Opencode Swarm Orchestration & Unrestricted Mode

[denyn1]

This PR introduces a major upgrade to Opencode by adding "Swarm Orchestration" capabilities.

Key changes:

1. Unrestricted Mode: Added a "God Mode" (unrestricted) in PermissionNext that bypasses all permission prompts when enabled.
2. Swarm Manager: Created a SwarmManager to orchestrate multiple agent sessions (up to 10,000) in parallel.
3. Agent Workflow: Implemented a specialized "PhD-level" workflow prompt injected into all swarm agents, guiding them to analyze, plan, and execute tasks autonomously.
4. Communication: Added a shared "Blackboard" memory and corresponding tools (read_blackboard, write_blackboard) for agents to share state.
5. Swarm Dashboard: Added a standalone Web UI (served at /swarm) to control the swarm, toggle modes, and visualize agent status.
6. API Routes: Added /swarm/api/* endpoints to support the dashboard and external control.

Verified with unit tests for Swarm Logic and Playwright for the Dashboard UI.
