docs: Strategic update integrating Hybrid Agents, MCP-Universe, and DOM Selector Drift defenses

[jgoldfoot]

🎯 What

Synthesizes recent 2026 industry research regarding MCP-Universe, hybrid agents, and DOM selector drift into the core BiModal Design methodology. It adds a new strategic proposal, a concrete implementation example for UI-to-API handoffs, and updates the core whitepaper and README.

💡 Why

Real-world evaluations show that the most successful agentic systems are "hybrid agents" that mix UI navigation with direct API/protocol calls to avoid brittle "DOM selector drift." Additionally, the emergence of the MCP-Universe benchmark shifts the focus toward multi-server environments. The framework must evolve beyond simple HTTP fetching and pure visual reasoning to address these new failure modes and agent architectures using standards-based methods (like <link rel="alternate"> and schema.org).

✅ Verification

1. Read the newly created files (docs/proposals/010-hybrid-agents-and-production-failure-modes.md, examples/hybrid-agent-mcp-handoff.md).
2. Verified the replace_with_git_merge_diff modifications to docs/whitepaper.md and README.md via git diff.
3. Ran pnpm run format to ensure Prettier compliance.
4. Ran pnpm test and pnpm run lint successfully. No regressions were introduced.
5. Requested and passed code review.

✨ Result

The BiModal Design framework now formally documents the challenge of DOM selector drift and the rise of Hybrid Agents, maintaining its position as the definitive standard for dual-mode interface design by integrating 2026 intelligence into actionable design patterns.
