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
+A warehouse system needs the quantity for a replenishment order of a storage
+bin. The calling program calls the function module {{P}}REPL_CALC. The
+calculation logic must be in the class {{P}}CL_REPL, because other programs
+also use this logic.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Function group {{P}}FG_REPL exists in package $TMP.
+- Function module {{P}}REPL_SAMPLE exists in this function group. It shows bin
+  information. Do not change it.
+- The class {{P}}CL_REPL does not exist. Create it first.
+
+# 4. Contract
+
+## 4.1 Class {{P}}CL_REPL
+- Package: $TMP.
+- The class is instantiable without parameters.
+- Public instance method calculate:
+  - importing iv_stock, type decfloat34
+  - importing iv_reorder_point, type decfloat34
+  - importing iv_target_stock, type decfloat34
+  - importing iv_pack_size, type decfloat34
+  - importing iv_min_qty, type decfloat34
+  - returning rv_qty, type decfloat34
+- The method has no exception. Call it only with a positive pack size.
+
+## 4.2 Function module {{P}}REPL_CALC
+- Function group: {{P}}FG_REPL.
+- Importing parameters:
+  - iv_stock, type decfloat34
+  - iv_reorder_point, type decfloat34
+  - iv_target_stock, type decfloat34
+  - iv_pack_size, type decfloat34
+  - iv_min_qty, type decfloat34
+- Exporting parameters:
+  - ev_qty, type decfloat34
+- Exceptions: invalid_pack_size.
+- The function module {{P}}REPL_CALC must call the method calculate of the class
+  {{P}}CL_REPL. Create and activate the class before you activate the function
+  module.
+
+# 5. Business rules
+1. If the pack size is not positive, the function module raises the exception
+   INVALID_PACK_SIZE. The class method is not called in this case.
+2. If the stock is greater than or equal to the reorder point, the
+   replenishment quantity is 0.
+3. Otherwise, the requirement is the target stock minus the stock.
+4. If the requirement is less than the minimum quantity, the requirement is the
+   minimum quantity. A minimum quantity below 0 counts as 0.
+5. If the requirement is not positive, the replenishment quantity is 0.
+6. Otherwise, round the requirement up to the next full multiple of the pack
+   size. The replenishment quantity is this multiple multiplied by the pack
+   size.
+
+# 6. Constraints
+- Release target: 7.58.
+- Use Clean ABAP. Keep each method below 40 statements.
+- Out of scope: do not change {{P}}REPL_SAMPLE. Do not create database tables.
+
+# 7. Acceptance
+- The function module and the class are active and have no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests for the function module in a global test class.
