agent-e2e-harness

Install and adopt Agent E2E Harness in an application: add the package and npx skills setup, create agent-e2e.config.ts, define seeded journeys, wire stack and cleanup resources, run agent-e2e dev with standard MCP clients, build proof loops from artifacts, and run agent-e2e verify in CI.

Run an independent adoption smoke test for Agent E2E Harness by spawning or directing a fresh agent in a clean consumer app, giving it only the app idea plus the agent-e2e-harness repo/skill pointer, then observing whether it can install the skill, build a journey, run agent-e2e verify, prove Dev MCP with tool calls, and report adoption learnings.
