Walkthrough

Changes

The project updates to SDK v42int5, changes wallet version defaults, adapts L1 invitation creation to the new URI response, moves shield fee estimation to the wallet manager, and adds CodeRabbit review configuration.

SDK v42int5 integration

Layer / File(s)	Summary
SDK version and review configuration .coderabbit.yaml, build.gradle, wallet/build.gradle	The project selects SDK v42int5, updates wallet version defaults to 12.0.0, and adds CodeRabbit review settings and path instructions.
L1 invitation adaptation wallet/src/de/schildbach/wallet/service/platform/sdk/SdkL1InviteCreation.kt	L1 invitation creation now returns an app-owned carrier with the funding outpoint and bearer URI. The funding outpoint is recovered from the persisted SDK invitation row.
Shield fee API update wallet/src/de/schildbach/wallet/service/platform/sdk/ShieldedBalanceServiceImpl.kt	Shield fee estimation now uses PlatformWalletManager.estimateShieldedFee.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 2a602

Invitation funding can complete before the app recovers and displays the resulting voucher, so cancellation followed by a retry could potentially fund a second voucher. The PR is mergeable with explicit owner awareness and follow-up to add durable recovery or idempotency for interrupted funding operations.
