Bound simctl launch and open-url to stop CLI integration flakes

[DjDeveloperr]

Summary

• Added timeout handling to the native process runner so wedged simctl invocations are killed instead of hanging indefinitely.
• Applied bounded timeouts to simulator launch and openurl calls in the Objective-C bridge.
• Expanded retry handling for transient launch and open-url failures so the integration harness can recover from temporary CoreSimulator stalls.

Testing

• cargo test --manifest-path server/Cargo.toml
• npm run build:cli
• npm run build:client
• npm run format:check
• SIMDECK_INTEGRATION_VERBOSE=1 npm run test:integration:cli
