Enhance CI pipeline documentation and improve git command handling

- Updated the `/ci` command documentation to clarify the execution steps for the CI pipeline, specifically regarding the rbx-dom section.
- Modified git command invocations in `CloneCommand` and `InitCommand` to include the `--no-verify` flag, allowing commits to bypass pre-commit hooks.
- Added null input handling for git commands in `CloneCommand`, `InitCommand`, and `Syncback` to prevent blocking on stdin.
