Add approval configuration for the delegated agents.

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

macOS 15.7.2 (24G325)

### Expected behaviour

Configurable option to allow some of the agents to run through delegate tool without additional approval.
Very useful for non interactive sessions

### Actual behaviour

Delegate tool requires additional approvals, which stops non-interactive sessions.

### Steps to reproduce

Example:
```md
....
Using tool: todo_list (trusted)
⋮
● TODO:
[x] Delegate to github-pr-agent: commit changes, create PR with template, reference issue, assign review group
[ ] Delegate to github-issues-agent: link PR to issue, move to 'In Review', set end date ⋮
● Completed in 0.0s

> Now I need to delegate to the github-pr-agent to create pull requests for the changes. Based on the terraform-agent output, there are changes
in two repositories that need PRs:

1. XXX1 repository
2. XXX2 repository

Using tool: delegate (trusted)
⋮
● Delegating task to agent
Agent: github-pr-agent
Description: Specialized agent for GitHub Pull Request operations
Task: Create pull requests for issue #72: ENI and Network Interface Tagging Compliance.
