CI hardening: required ABI surface + local anvil integration gates

[snissn]

Implements the testing/CI hardening plan focused on preventing ABI/UI drift and enforcing local-chain integration on every PR.

What changed

• Added ABI surface regression test:
  • test/testUiAbiSurface.js
  • Asserts generated ABI contains all UI-required functions per collection (listIds*, get*(uint256), create*, optional update*/transfer*, and delete*).
• Added local E2E integration test:
  • test/integration/testCliLocalIntegration.js
  • Covers th preview auto-deploy on anvil, manifest publication, and faucet endpoint behavior.
• Split scripts for CI gating:
  • pnpm test for static/unit/template checks.
  • pnpm test:integration for local-chain E2E checks.
• Improved UI ABI mismatch diagnostics:
  • Added ABI function guards in UI contract call paths with explicit collection/function error messaging.
• CI workflow split into two required jobs:
  • static
  • integration-local (installs Foundry, checks anvil, runs integration tests).
• README updated with testing/CI usage.

Validation

• pnpm test
• pnpm test:integration
• pnpm typecheck
