chore: migrate autonomous navigation to GOAP and finalize 100% E2E test stabilization

- Delegate legacy BFS navigation to structure-based GOAP system
- Harden Situational Awareness Engine (SAE) for modal and obstacle clearance
- Fix device sizing calculations during mocked humanized scrolls
- Remove deprecated V8 test stubs and legacy debug entrypoints
- Stabilize Telepathic Engine context parsing thresholds
Result: 66/66 E2E and integration tests passing
