refactor(perception): Purge legacy coordinate hacks from feed and telepathic engines

Removed the hardcoded structural fallback bypasses for bottom navigation tabs to ensure 100% autonomous visual inference. Expanded the VLM intent resolution prompt with explicit spatial heuristics for bottom navigation (e.g., 'profile tab is the avatar icon at the bottom right') to prevent LLaVA hallucinations without resorting to XML resource-id hacks. Added E2E visual test proof.
