test(ios): high-level E2E + touchfile registration

8 E2E scenarios: codegen against SwiftUI fixture, daemon spawn + stub StateServer, schema-mismatch rejection, full agent loop, multi-agent contention, tailnet allowlist gating, capability-tier enforcement. Registered as gate-tier in E2E_TOUCHFILES + E2E_TIERS so diff-based selection picks up iOS work without slowing every PR.
