feat(autonomy): refactor navigation engine to autonomous goals with TDD

- Added strict TDD coverage for all autonomous changes.
- Implemented GrowthBrain.get_current_goal to select high-level objectives.
- Replaced procedural orchestrator with GoalExecutor in bot_flow.
- Purged hardcoded resource-ids in dm_engine in favor of ScreenIdentity.
- Removed regex parsing in unfollow_engine in favor of telepathic semantic extraction.
