Add claude-yolo adapter

[duncankmckinnon]

Summary

• add a built-in claude-yolo adapter that launches Claude Code with --dangerously-skip-permissions
• preserve the existing claude adapter and its restricted --allowedTools configuration
• expose the new adapter through generated agent configs, CLI listings/help, profiles documentation, and Headroom routing
• document the security implications and opt-in usage

Why

Workbench previously offered only the restricted Claude adapter. Users running Workbench inside an appropriately isolated environment had no built-in way to opt into Claude Code's non-interactive permission bypass without maintaining a custom adapter override.

This adds that explicit opt-in while keeping the safer existing adapter as the default.

Impact

Users can run:

wb run plan.md --agent claude-yolo

Existing claude behavior is unchanged. wb agents init now includes both Claude configurations.
