Asc Revenuecat Catalog Sync

This reconciles your App Store Connect subscription catalog with RevenueCat's product configuration using both the asc CLI and RevenueCat MCP server. You run it in audit mode first to see the drift between ASC subscriptions, IAPs, and your RevenueCat products, entitlements, and offerings, then apply mode to create missing items and wire up the mappings. It matches on store identifiers, won't auto-delete anything, and handles the full flow from creating ASC subscription groups down to attaching products to RevenueCat packages with the right identifier conventions. The main value is deterministic bootstrapping and preventing the usual catalog drift headaches before release. Needs both systems already authenticated and you'll want a write-enabled RevenueCat API key for applying changes.
