Claude Code runtime always launches in dontAsk, preventing agents from executing commands

## Describe the bug

After updating to Buzz v0.5.5, every Claude Code agent starts in `dontAsk` permission mode.

As a result, my agents can no longer execute shell commands. They silently fail because command execution is denied.

Running Claude Code directly from Terminal works correctly.

## Steps to reproduce

1. Update to Buzz v0.5.5.
2. Configure an agent to use the Claude Code runtime.
3. Ask the agent to perform any action that requires running a command.
4. Open the Activity panel.

## Actual behavior

The Activity panel shows:

```
Mode: dontAsk
```

The agent reports that it cannot execute commands because permissions are denied.

Example:

> "permission to run commands is switched off in this session."

This prevents the agent from reading the repository, executing Git commands, or doing any normal development work.

## Expected behavior

Buzz should either:

- Respect Claude Code's configured/default permission mode, or
- Allow selecting the permission mode (Auto, acceptEdits, bypassPermissions, etc.) for the Claude Code runtime.

At the moment, Buzz appears to always launch Claude Code in `dontAsk`.

## Version and platform

- Buzz version: 0.5.5
- OS: macOS 15
- Hardware: Apple Silicon (M1 Max)

## Additional context

Launching Claude Code manually from Terminal with:

```bash
claude --permission-mode bypassPermissions
```

works correctly.

The problem only occurs when Claude Code is launched through Buzz.

I've attached screenshots showing:

- Buzz Activity reporting `Mode: dontAsk`
- Claude Code working normally in `bypassPermissions`
