Add shape selectors, LLM stream timeouts, MultiSelect questions, and test coverage

- Stylesheet: add bare-word Shape selector (specificity between Universal and Class)
- LLM: apply per_step timeout to connection and total timeout to stream (Section 4.7)
- Interviewer: add MultiSelect question type alongside MultipleChoice
- Session: move SessionStart/SessionEnd to initialize()/close(), deduplicate close logic
- Engine: return Ok(fail outcome) instead of error when goal gate unsatisfied with no retry_target
- Docker: mark Docker-dependent tests with #[ignore]
- Validation: add extensive unit test coverage for all rule types
- Integration: update tests to match engine/fidelity changes
