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 freight forwarder calculates the price of an outbound shipment. The
+calculation service receives the gross weight, the volume, the transport
+distance, and the current fuel index. It returns the freight components and a
+reason code.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The interface {{P}}IF_FREIGHT_CALC exists in package $TMP. It is active.
+- The interface defines the types TY_REASON, TY_AMOUNT, TY_WEIGHT, TY_VOLUME,
+  TY_DISTANCE, TY_FUEL, and TY_RESULT.
+- The interface defines the constant structure C_REASON with the components
+  OK, WEIGHT, VOLUME, DISTANCE, and FUEL.
+- The interface defines the instance method CALCULATE with the importing
+  parameters IV_WEIGHT_KG, IV_VOLUME_M3, IV_DISTANCE_KM, IV_FUEL_INDEX and the
+  returning parameter RS_RESULT.
+
+# 4. Contract
+- Create the class {{P}}FREIGHT_CALC in package $TMP.
+- The class is public, final, and has a public constructor without parameters.
+- The class implements {{P}}IF_FREIGHT_CALC.
+- Do not add other public methods.
+
+# 5. Business rules
+All amounts are in euro. Apply the rules in this sequence.
+1. If IV_WEIGHT_KG is less than or equal to 0, return the reason WEIGHT. Set
+   all amounts and the chargeable weight to 0.
+2. If IV_VOLUME_M3 is less than 0, return the reason VOLUME. Set all amounts
+   and the chargeable weight to 0.
+3. If IV_DISTANCE_KM is less than or equal to 0, return the reason DISTANCE.
+   Set all amounts and the chargeable weight to 0.
+4. If IV_FUEL_INDEX is less than 0 or greater than 100, return the reason FUEL.
+   Set all amounts and the chargeable weight to 0.
+5. The volumetric weight is IV_VOLUME_M3 multiplied by 250.
+6. The chargeable weight is the greater of IV_WEIGHT_KG and the volumetric
+   weight.
+7. The base freight is 45.00. For each full or partial 100 kg by which the
+   chargeable weight is greater than 1000 kg, add 6.50.
+8. The distance freight is 0.00 for a distance up to and including 100 km. For
+   each full or partial 100 km by which IV_DISTANCE_KM is greater than 100 km,
+   add 9.00.
+9. The fuel freight is the sum of the base freight and the distance freight,
+   multiplied by IV_FUEL_INDEX, divided by 100. Round the result to 2 decimal
+   places. Round a half away from zero.
+10. The total is the sum of the base freight, the distance freight, and the
+    fuel freight.
+11. Return the reason OK.
+
+# 6. Constraints
+- Release target: 7.40 SP05. Do not use syntax that is newer than 7.40 SP05.
+  For example, do not use COND, SWITCH, REDUCE, FOR, or LET.
+- Coding standards: Clean ABAP. Method length below 40 statements. No global
+  variables. No comment that restates the code.
+- Out of scope: do not change {{P}}IF_FREIGHT_CALC.
+
+# 7. Acceptance
+- The class is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.
