Add ORCH — CLI orchestrator for Claude Code agent teams

[oxgeneral]

Adding ORCH to the Framework Extensions section.

ORCH is a CLI orchestrator that coordinates Claude Code, OpenCode, Codex, Cursor, and shell scripts as a typed AI team. Key features:

• Validated state machine: todo → in_progress → review → done (with auto-retry and stall detection)
• Inter-agent messaging: agents communicate via orch msg send
• Goal-based autonomous mode: high-level goals decomposed into tasks assigned to idle agents
• TUI dashboard: real-time visibility across all agents, tasks, and goals
• Zero infrastructure: file-only state (.orchestry/ YAML+JSONL)
• 1647 passing tests, MIT license
