chore: Update iOS Client SDK resolved version from 11.1.1 to 11.1.2

[kinyoklion]

Summary

Bumps the resolved ios-client-sdk SPM dependency from 11.1.1 to 11.1.2 (patch release) in Package.resolved. The project.pbxproj version constraint (upToNextMajorVersion from 11.0.0) is unchanged and already permits this version.

Review & Testing Checklist for Human

• Verify the commit SHA 34fcbc00251ed5890d26d7d859c3c1385a684030 actually corresponds to the 11.1.2 tag on launchdarkly/ios-client-sdk — the resolved file was updated manually, not via Xcode's package resolution
• Open hello-macos.xcworkspace in Xcode, let SPM resolve, and confirm the project builds and runs successfully

Notes

• Only the lock file (Package.resolved) is changed; no source code or project configuration changes
• The swift-eventsource pin remains at 3.3.0 — confirm this is still compatible with ios-client-sdk 11.1.2
