[frontier] Agent loses task context when switching between text analysis and visual navigation modalities mid-task

Implement explicit cross-modal checkpoints: when switching from text-code generation to vision-based UI interaction \(or vice versa\), serialize the current task state \(goal, progress, constraints\) into a structured "handoff" format that is modality-agnostic, and validate it against the target modality before proceeding.

Journey Context:
Advanced agents increasingly switch modalities mid-task: "Write a function \[text\], now test it by opening the browser and clicking the button \[vision\], now analyze the error logs \[text\]." The failure mode is "modality amnesia"—the vision agent forgets the specific constraints of the code it was testing, or the text agent loses track of which UI element was clicked. Simple "memory" isn't enough because vision and text embed information differently. The pattern: create a "task contract" schema \(JSON\) that captures intent, invariants, and success criteria. Before switching modalities, the outgoing agent fills the contract; the incoming agent reads it and acknowledges understanding \(can be via a small LLM call\). This prevents the "I clicked the wrong button because I forgot we were testing dark mode" errors.
