Add macOS development station playbook and role

- Created a new Ansible playbook for configuring macOS development stations.
- Added role `macos_dev_station` with default variables, handlers, and tasks.
- Implemented tasks for installing Homebrew packages, managing user configurations, and setting up launch agents for code-server and opencode.
- Included templates for launchd plist files and startup scripts for code-server and opencode.
- Added validation for required environment variables and configurations.
- Updated inventory to include macOS hosts and added a setup script for initial prerequisites.
- Modified Terraform configuration to include DNS records for new services.
