Add iOS SwiftUI verification rule

[Nagarjuna2997]

Adds a scoped canonical .mdc rule for durable storage, failed writes, corrupt loads and simulator acceptance evidence. It complements the existing general SwiftUI guidelines with a verification-focused workflow.

Adapted with attribution from https://github.com/Nagarjuna2997/ios-agent-skill (MIT). The Reading List demo passed 3 unit tests and 2 UI tests; real Claude loop repair remains unverified and is labelled separately. The rule preserves deployment targets and existing architecture and does not auto-install tools.

Checked existing entries and submissions. Uses required description/globs/alwaysApply frontmatter and a Mobile Development entry. Submitted with AI assistance on behalf of the maintainer.
