Generator: pilot analysis and fixes; G0002-G0021 tasks; handover notes merged

- Static bundle checks (name length, seed type, reserved words, contract test classes,
  testclasses_file), local abaplint parser check before SAP, max_tokens, robust JSON parse
- Runner: G2 for CDS views with parameters, contract_check detail in report
- G0020 and G0013 fixed by review and revalidated (oracle 100, null 0)
- Pilot results in docs/faz1-tasarim.md 11e; handover notes merged into CLAUDE.md and docs

+# 1. Goal
+Show every open order together with the name and country of its customer. A
+list report and an OData service read this data, so the data must be prepared
+in the database, in a CDS view entity.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Table {{P}}CUST (customer master), package $TMP.
+  Key: CUST_ID (CHAR 10). Further fields: CUST_NAME (CHAR 40), COUNTRY (CHAR 3).
+- Table {{P}}ORD (order header), package $TMP.
+  Key: ORDER_ID (CHAR 10). Further fields: CUST_ID (CHAR 10), ORDER_DATE (DATS),
+  STATUS (CHAR 1).
+  STATUS is 'O' for an open order and 'C' for a closed order.
+
+# 4. Contract
+- Create the CDS view entity {{P}}I_ORDER in package $TMP.
+- Elements, with these names: ORDER_ID (key), CUST_ID, ORDER_DATE,
+  CUSTOMER_NAME, COUNTRY.
+- Define an association named _Customer in {{P}}I_ORDER. The association has
+  cardinality [0..1] and points to the customer master table {{P}}CUST. The
+  association condition compares the CUST_ID of the order with the CUST_ID of
+  the customer.
+- Expose the association _Customer in the element list of {{P}}I_ORDER and read
+  CUSTOMER_NAME and COUNTRY with path expressions through this association.
+- The view entity has no authorization check (#NOT_REQUIRED).
+
+# 5. Business rules
+1. {{P}}I_ORDER shows one row for each order with STATUS 'O'. An order with
+   STATUS 'C' is not shown.
+2. CUSTOMER_NAME is the CUST_NAME and COUNTRY is the COUNTRY of the customer
+   whose CUST_ID is the CUST_ID of the order.
+3. If an order has a CUST_ID for which no customer exists, the order is still
+   shown. CUSTOMER_NAME and COUNTRY are then empty.
+4. ORDER_ID, CUST_ID and ORDER_DATE are the values of the order.
+
+# 6. Constraints
+- Release target: 7.58.
+- Coding standards: Clean ABAP.
+- Out of scope: do not change {{P}}CUST and {{P}}ORD.
+
+# 7. Acceptance
+- The view entity is active and has no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests with CL_CDS_TEST_ENVIRONMENT in a global test class.
