IAP Finalizer

Finish a one-time in-app purchase on the store side: price + localization, the two fields the asc-metadata MCP can't set (it exposes only reference name / review note / family-sharing). Moves an IAP from MISSING_METADATA → READY_TO_SUBMIT so it can ship with the build.

This finalizes; it does not define. The product id, tier, and price decision come from Phase 4 (Monetization / StoreKit). The ASC IAP record must already exist (created via the MCP create_iap or the ASC UI). This skill sets the metadata on that existing record.

Where it fits (read the seams)

• Not Phase 4. Phase 4 builds the IAP into the app (StoreKit 2, paywall) and decides the price. This is Phase 6 store-metadata finalization.
• Price = one source of truth. Do not re-ask the price. Read it from the monetization decision in .planning/ (e.g. MONETIZATION.md / PLAN.md); only confirm it. Re-eliciting risks drift from the paywall/StoreKit price.
• Not promoted-iap. That generator displays promoted IAPs in-app; this sets ASC price/localization. Different jobs.
• One-time IAPs only. Subscriptions are a separate ASC flow (groups/offers) — out of scope here.
