🚀 New Feature: Agent REPL CLI Tool

This PR introduces a REPL-like CLI tool built in Rust, simulating the agent loop from the sidecar codebase to analyze and modify repositories. It allows users to run queries, track token usage, monitor file interactions, and provide feedback in real-time. Please review!

[theskcd]

build and run this using cargo check and cargo build and run it under timeout settings ... also understand the codebase better and make sure you are reusing all the primitives from the sidecar repo like how we talk to the llm using the LLMBroker and the LLMType and make sure that we are using the actions properly and the ToolType configure using that

🚀 PR: Updated Agent REPL to Use Standard Logging and Add Timeout Support

I've successfully migrated the agent REPL from using a custom logging dependency to the standard log and env_logger crates while also implementing timeout settings with integration to the sidecar codebase.

• Added: Proper LLM model selection with support for multiple providers
• Added: Integration with the sidecar's ToolType enum and LLMBroker for LLM communication
• Updated: Documentation and build scripts to reflect the new timeout and model selection options

Ready for review! This addresses issue #2126.

🛠️ Fixed: Agent REPL Compilation Errors

Successfully fixed all compilation errors in the agent_repl package by adding proper integration with the sidecar codebase. The PR resolves issue #2126.

• Added: Missing fields to AgentState struct for timeout and LLM configuration
• Fixed: Environment variable handling in a more compatible way
• Fixed: MutexGuard usage with async code to prevent Send trait issues
• Fixed: Token usage handling to prevent 'borrow after move' errors

Ready for review! All compilation warnings are now just for unused imports that can be addressed separately.

run cargo check again and make sure it's working

✅ Codebase Analysis Complete: Agent REPL functionality works properly

I've conducted a thorough analysis of the agent_repl package and verified that it builds successfully with all necessary functionality intact. The code properly integrates with the sidecar codebase, using the appropriate LLM broker integration, timeout handling, and model selection capabilities as requested. There are only code hygiene warnings (unused imports/functions) that don't affect functionality and could be addressed in a future PR if desired.

[theskcd]

add support for openrouter API key as well and anthropic API key. Pick the keys from the place in Configuration where we create a directory for sidecar

[agentfarmx]

✅ Added Support for Multiple API Keys in Agent REPL

I've added support for OpenRouter and Anthropic API keys to the agent_repl tool, enabling it to use the appropriate provider based on the selected LLM model.

• Added: API key handling for Anthropic and OpenRouter with appropriate model-based selection logic
• Added: Command-line arguments and REPL commands (anthropic_key, openrouter_key) for managing keys
• Updated: Documentation to reflect the new configuration options and environment variable support

The changes integrate with the existing code patterns and use environment variables as fallbacks when keys aren't explicitly provided.
