feat(plugin): add dispatch, status, recall, scan commands

New slash commands for the agentic system:
- /dispatch — dispatch subagent to sandboxed workspace
- /status — show workspace status (running/blocked/completed)
- /recall — search OpenBrain memories
- /scan — find actionable Forge issues

Fix MCP URL: api.lthn.sh/mcp → mcp.lthn.sh (subdomain routing).
