simless 0.1.2

• Demo app and fidelity page. Examples/SimlessDemo has seven common screens, and docs/fidelity.md shows each one rendered by the iOS Simulator and by simless, side by side, with what differs.
• Crash fix: screens with Form, Toggle or Picker no longer crash the host. 0.1.1 overrode the idiom to .phone, which makes SwiftUI's control styles recurse until the stack overflows on the Mac. Phone canvases keep phone size classes and safe areas; the idiom stays iPad, and renders say so.
• Accessibility trees match what VoiceOver sees. Elements are no longer descended into, and containers that list their elements no longer also contribute their subviews. That removes duplicates such as a Toggle row's switch, a Picker's value text and navigation titles, which accounted for over half the issues reported on the demo app.
• Simulator render window. In simless calibrate, the render window is created on first use, so a scene that connects late no longer fails every render with a misleading "unknown fixture".
• Calibration report. simless calibrate --png <dir> saves both renders of every screen and writes a side-by-side report.md; --dark adds dark mode. Text that only renders slightly wider, and elements exposed with a different role, are reported as minor instead of failing the screen.
• Projects without a test plan. Their test runs use the older .xctestrun format, which simless now also handles.
• Signing team. When a project sets no DEVELOPMENT_TEAM, simless uses team from .simless.json, SIMLESS_TEAM, or the only Apple Development identity in the keychain.
