[FEATURE] Add --preset flag for conversation presets

[jwesleye]

Feature Description

Load predefined conversation presets (system prompts, behavior, settings) for common use cases.

Problem/Motivation

Different tasks need different conversation styles. Manually configuring each time is tedious.

Proposed Solution

chat_loop myagent --preset code-review

# Presets could be stored in ~/.chat_presets/
# code-review.yaml:
#   prompt: "Act as a senior code reviewer..."
#   temperature: 0.3
#   behavior: strict

# Other presets:
# - brainstorming
# - debugging  
# - documentation
# - teaching

Benefits

• Consistent behavior for task types
• Share presets across team
• Quick task switching
• Best practices codified

Priority

• Critical
• High
• Medium
• Low

Closing as out of scope for this AWS Strands-focused CLI tool.

This project is focused on providing a simple, efficient command-line interface for AWS Strands agents. Advanced features like workflow automation, collaboration tools, and complex UI enhancements would add significant complexity without serving the core use case.

We're keeping the scope focused on:

• Solid AWS Strands agent integration
• Essential CLI features (history, templates, sessions)
• Developer productivity (debugging, validation)
• Simple, maintainable codebase

Thank you for the suggestion!
