Add SwiftUI minimal display-list LLDB hook

[Kyle-Ye]

Summary

• Add an LLDB command that redirects SwiftUI DisplayList.description calls to minimalDescription inside the debugged process.
• Avoid breakpoint-based interception and restore the original instruction and conflicting breakpoint locations when disabled.
• Automatically import the command for the SUI_Example, SUI_HostingExample, and SUI_TestingHost schemes.
• Document setup, usage, compatibility, and recovery behavior.

Motivation

SWIFTUI_PRINT_TREE=1 always prints the full display-list description, which becomes difficult to scan for large view hierarchies. SwiftUI also provides a compact minimalDescription, but does not expose an environment switch for selecting it.

Validation

• Confirmed that .lldbinit-swiftui imports the command independently of LLDB's working directory.
• Regenerated the Example workspace and verified the custom LLDB init path on all three SwiftUI run schemes.
• Verified minimal output, conflicting-breakpoint handling, and instruction restoration on an arm64 iOS 18.5 Simulator.
