✨ Add project configuration command

Add ability to create and manage project-specific configs

This change adds a new `project-config` command that allows teams to share
common settings via version control without exposing API keys:

- Create .irisconfig files in repository root with shared settings
- Automatically merge project and personal configs at runtime
- Implement security measures to prevent API keys in project configs
- Add CLI options for managing model, token limits, and parameters
- Include comprehensive tests for config security and merging
- Refactor config handling for better code organization

Project configs enable teams to standardize on models and settings
while keeping personal API keys private.
