Add portable mobile app testing guidance

[juliusmarminge]

Summary

• Add repository-owned skills for isolated T3 Code Mobile verification on iOS and Android
• Configure pinned XcodeBuildMCP integration for Codex and Claude Code, plus pinned serve-sim guidance
• Update agent instructions to run one focused integrated pass for each affected client surface
• Expose connection-sheet actions as semantic mobile buttons so simulator automation can complete pairing

Validation

• Validated all four repository testing skills
• Parsed the JSON, TOML, and agent YAML configuration
• Passed focused formatting, mobile lint, and @t3tools/mobile typecheck
• React Doctor: 100/100 for the branch diff
• Fresh context-free iOS agent pass paired to isolated state and found the seeded project through XcodeBuildMCP

Full repository tests were not run, in accordance with the focused local-verification policy.

Note

Add mobile app testing guidance and iOS simulator tooling configuration

• Adds skill documentation and agent configs for ios-debugger-agent, ios-simulator-browser, and test-t3-mobile to guide agents through building, launching, and testing iOS/Android apps against a disposable T3 backend.
• Configures the xcodebuildmcp MCP server in .mcp.json and .codex/config.toml with simulator, UI automation, debugging, and logging workflows enabled.
• Updates AGENTS.md to require one integrated verification pass per affected client surface (web and mobile) and prefer iOS with serve-sim on compatible macOS hosts.
• Adds accessibility props (accessibilityLabel, accessibilityRole, accessibilityState) to ConnectionSheetButton to support semantic UI automation.
