Subject: [PATCH] Add Linux development station role with systemd services for
 code-server and OpenCode

- Implemented handlers for restarting code-server and OpenCode services.
- Created main tasks for setting up a Linux development station, including user management, package installation, and configuration.
- Added validation for OpenCode server credentials and code-server password.
- Introduced tool package management for npm, uv, and go installers.
- Developed templates for systemd service units for code-server and OpenCode.
- Included scripts for starting code-server and OpenCode with SSH agent support.
- Updated inventory and Terraform configuration to include new development host.
