## High-level PR Summary
This PR implements a comprehensive renaming of "offer" to "product" and
"offer group" to "product catalog" throughout the codebase. The changes
include database migrations, schema updates, API compatibility layers,
function renames, and updates to client and server implementations.
Backwards compatibility is maintained through migration layers that
handle requests using the old terminology, translating them to the new
terminology before processing. The PR includes documentation of this
approach in CLAUDE-KNOWLEDGE.md. This rename affects multiple parts of
the system including the database schema, API endpoints, error types,
and SDK interfaces.

> [!IMPORTANT]
> Renames 'offer' to 'product' and 'offer group' to 'product catalog'
across the codebase, updating database schema, API endpoints, and
application logic for consistency and backward compatibility.
>
> - **Database**:
> - Rename columns `offer` to `product` and `offerId` to `productId` in
`OneTimePurchase` and `Subscription` tables in `migration.sql`.
> - **API & Migrations**:
> - Update API endpoints to accept `product_id`/`product_inline` instead
of `offer_id`/`offer_inline`.
> - Add `v2beta5` compatibility layer to map legacy `offer` fields to
`product` equivalents.
> - **Shared Schemas**:
> - Rename `offerSchema` to `productSchema` and related schemas in
`schema-fields.ts`.
> - **Server Implementation**:
> - Update `createCheckoutUrl` method in `server-app-impl.ts` to use
`productId`/`InlineProduct`.
> - **Tests**:
> - Update tests to reflect renaming in `backend-helpers.ts` and other
test files.
> - **Miscellaneous**:
> - Remove dummy data related to offers in `dummy-data.tsx`.
> - Update documentation and comments to reflect terminology changes.

> [!NOTE]
> Renames offers→products and groups→catalogs end-to-end (DB, APIs,
schemas, UI, SDK, docs), adding v2beta5 compatibility to accept legacy
offer fields while updating all internals.
>
> - **Backend/DB**:
> - Prisma migration: rename `offer`/`offerId`→`product`/`productId` in
`OneTimePurchase` and `Subscription`.
> - Update Stripe webhook, purchase-session, and internal test-mode
flows to use `product*` metadata/fields.
> - **API & Migrations**:
> - Latest endpoints now accept `product_id`/`product_inline`.
> - Add `v2beta5` compat layer mapping legacy `offer_id`/`offer_inline`
to product equivalents; responses alias conflicting products.
> - **Shared Schemas/Errors/Config**:
> - `offerSchema`→`productSchema`,
`inlineOfferSchema`→`inlineProductSchema`, prices/types renamed.
> - KnownErrors renamed (e.g., `PRODUCT_DOES_NOT_EXIST`).
> - Config: `groups`→`catalogs`, defaults/migrations updated; improved
override validation messages; ID regex loosened; formatter tweaks; add
schema fuzzer tests.
> - **Payments Lib**:
> - Rename APIs and logic (`offers`→`products`, `groupId`→`catalogId`),
subscription and item-quantity computation updated.
> - **Dashboard/UI**:
> - Routes, dialogs, editors, tables, and code samples switched to
products/catalogs; removed offers dummy data.
> - **SDK/Template**:
> - Client/server `createCheckoutUrl` now uses
`productId`/`InlineProduct`.
> - **Tests/Docs/Utilities**:
> - E2E and unit tests updated; add legacy (pre-rename) tests.
> - Docs and knowledge base revised; minor script tweaks (recent-first,
limits).

- Added new config json schema and helper functions
- Separated the internal project and client project so we can later
change the internal project APIs without breaking backward compatibility
- Added database to config json and config json to project type so we
can test and compare the result in production
