feat(amazonq): Add code symbol support in context selection of Q Chat (#6831)
## Problem We can select @file and @folder in the Q chat menu. But we should be able to also let user select class, function and these symbols. ## Solution Support @code in the context selection of Q chat. <img width="742" alt="Screenshot 2025-03-21 at 2 15 34 PM" src="https://github.com/user-attachments/assets/85f99420-831f-4683-bdfa-7a4cd441cf6a" /> --- - Treat all work as PUBLIC. Private `feature/x` branches will not be squash-merged at release time. - Your code changes must meet the guidelines in [CONTRIBUTING.md](https://github.com/aws/aws-toolkit-vscode/blob/master/CONTRIBUTING.md#guidelines). - License: I confirm that my contribution is made under the terms of the Apache 2.0 license.
