feat(cli): add CLI prompt simulation and testing scripts

- Introduced `simulate-cli-prompt.js` to simulate various prompt formats and display the final content passed to the CLI.
- Added `test-shell-prompt.js` to test actual shell execution of different prompt formats, demonstrating correct vs incorrect multi-line prompt handling.
- Created comprehensive tests in `cli-prompt-parsing.test.ts` to validate prompt parsing, including single-line, multi-line, special characters, and template concatenation.
- Implemented edge case handling for empty lines, long prompts, and Unicode characters.
