Add Feature Rollout support to the Swift SDK. Feature Rollouts are a new experiment rule type that combines Targeted Delivery simplicity with A/B test measurement capabilities. - Add optional `type` field (ExperimentType enum) to the Experiment model with valid values: ab, mab, cmab, td, fr - Add config parsing logic to inject the "everyone else" rollout variation into feature rollout experiments (type == .featureRollout) - Add traffic allocation entry (endOfRange=10000) for the injected variation - Add `getEveryoneElseVariation` helper to extract the last rollout rule's first variation - Rebuild experiment lookup maps after injection so decisions use updated data - Add 10 unit tests covering injection, edge cases, and backward compatibility

There was a problem hiding this comment.
Looks good to me. A couple of comments added.

…parsing Unknown experiment type values (e.g., "new_unknown_type") no longer crash datafile parsing. They are silently dropped to nil, aligning with other SDKs for forward compatibility. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
Adds Feature Rollout support to the Swift SDK. Feature Rollouts are a new experiment rule type that combines Targeted Delivery simplicity with A/B test measurement capabilities. During project config parsing, the "everyone else" variation from the flag's rollout is injected into any experiment with type "fr", enabling correct evaluation without changes to decision logic.
