Replace ios-deploy with devicectl for physical iOS devices

[enfipy]

Goal

Use Xcode's official devicectl for physical iOS devices and remove ios-deploy completely.

Scope

• Discover available paired devices from structured devicectl output.
• Select --device-id exactly; auto-select only when unambiguous and report actionable errors otherwise.
• Install the signed .app and launch its bundle identifier.
• Define crossbundle run ios --device modes consistently:
  • default: attach the application console;
  • --detach: launch and return immediately;
  • --debug: start and attach an interactive LLDB session; conflict with --detach.
• Preserve the existing simctl path for Simulator runs.
• Detect unsupported Xcode versions with a clear remediation message.
• Update doctor, tests, and documentation to require Xcode's device tooling only.
• Remove all ios-deploy commands, checks, documentation, and fallback behavior.

Keep command construction and output parsing in crossbundle-tools; the CLI should expose Crossbundle concepts rather than raw devicectl flags. Prefer machine-readable output and typed parsing over human-output matching.

Done when

crossbundle run ios --device can select, install, and launch on a modern physical device with predictable attached, detached, and debug behavior; failures identify the device or Xcode action required; Simulator behavior is unchanged; and the repository contains no ios-deploy integration or setup requirement.
