Add Amazon Q Cli as provider

[SHTO88]

Please add Amazon Q CLI (by AWS) as a provider in Roo-Code, using the same subprocess integration pattern as Claude Code CLI.

Why This Matters

• AWS-Native AI Coding: Deep integration with AWS services for developers building in the AWS ecosystem.
• Enterprise-Grade Security: Built-in IAM-based authentication and compliance features.
• Optimized for AWS Workflows: Tailored for Lambda, ECS, DynamoDB, and other AWS resources.

Technical Feasibility

• Use the existing Claude Code CLI integration pattern (stdin/stdout via subprocess).
• Authentication: Leverage AWS CLI credentials or IAM roles for secure access.
• Requires installation of AWS CLI + Amazon Q CLI setup (already common in AWS developer environments).

Benefits

• Devs: Tight AWS integration for code generation, refactoring, and resource orchestration.
• Organizations: Aligns with existing AWS security, billing, and governance.

Comparison with Claude Code CLI

Feature	Claude Code CLI	Amazon Q CLI (proposed)
Cost	Paid	Likely included with AWS pricing tiers
Provider	Anthropic	AWS
Model	Claude Sonnet 4	Amazon Q (AWS LLM)
Auth	Auth	IAM credentials / AWS CLI config

This integration would bring enterprise-grade AI coding with AWS-native benefits to Roo-Code, making it the ideal solution for AWS developers, teams, and organizations that want secure, integrated, and scalable AI coding assistance.
