Amazon Q: Add Trust ability when running commands

**Is your feature request related to a problem? Please describe.**
It's a pain having to Allow every single action. Both Kiro CLI and Kiro IDE allow to Trust actions. I really like how Kiro IDE does it, with a specific action, or a walk-up-the-tree of what action is allowed. And also being able to edit the trusted actions via a file.

When is this functionality coming to the Amazon Q IDE plug-in?

**Describe the solution you'd like**
Similar to Kiro IDE, when running a command, the option should not just be `Allow`, it should be `Y/N/T`, where `T` is Trust. After selecting `T`, the user is presented with the specific command or a portion of the command higher-up the command tree.
eg.
```
dotnet run -- ../My.sln --dostuff
dotnet run --
dotnet run
```

The issue names the Amazon Q IDE plug-in and its command-running approval prompt, but no repository file or test. Begin by locating that prompt and reviewing how Kiro IDE represents trusted commands; done should include a Y/N/T flow, command-tree scope selection, and an editable trust file.
