Closes #82

Add a comprehensive test suite covering the TUI module and streaming
execution infrastructure to improve code quality and prevent regressions.

New test files:
- tests/tui_snapshot_tests.rs: 20 tests for TUI rendering using
  ratatui's TestBackend for deterministic output verification
- tests/tui_event_tests.rs: 36 tests for keyboard navigation,
  scroll behavior, and view transitions
- tests/streaming_integration_tests.rs: 28 tests for NodeStream,
  MultiNodeStreamManager, and streaming execution

New benchmark file:
- benches/large_output_benchmark.rs: Performance benchmarks for
  large output handling, RollingBuffer overflow, concurrent multi-node
  streaming, and TUI rendering

New dev-dependencies:
- insta 1.34: Snapshot testing
- criterion 0.5: Benchmarking
- mockall 0.12: Mocking for integration tests

All 84 new tests pass successfully.
