- Added support for generating test cases using agents and scripts through the new `LoadFromAgent` and `LoadFromScript` methods in the loader.
- Enhanced the `RunTests` method to handle different input sources, including agent-driven and script-based test case generation.
- Introduced a `--dry-run` flag to allow users to preview generated test cases without executing them.
- Updated relevant documentation in DESIGN_V2.md and TODO_V2.md to reflect the new features and implementation status.
- Added a `noop` check in multiple logging methods (`LLMComplete`, `ToolStart`, `ToolComplete`, `HookStart`, `HookComplete`, and `HistoryLoad`) to prevent logging when the logger is in no-operation mode.
- Improved command handling in `root.go` by removing minimum argument requirements for commands and providing help output when no arguments are given.
- Introduced an `agent` command for better organization of agent-related functionalities in the CLI.
- Implemented automatic detection of the application root directory in `run.go` to streamline the application startup process.
- Cleaned up debug print statements in `config.go` to reduce clutter in the output.
