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 retail company gives loyalty discounts to its customers. A checkout program needs
+three values: the loyalty tier of a customer, the discount percent of a tier, and
+the number of points that a customer still needs for the next tier. The program
+calls one class for these three values.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The interface {{P}}IF_LOYALTY_RULES exists in package $TMP. It is active.
+- The interface declares the type of a point value, the type of a tier, the
+  constants for all tiers, and three methods. This document does not repeat the
+  signature of the interface. Read the interface before you start.
+- The three methods are:
+  * the method that returns the tier for a point value,
+  * the method that returns the discount percent of a tier,
+  * the method that returns the number of points that are missing for the next tier.
+
+# 4. Contract
+- Create the class {{P}}LOYALTY_EVALUATOR in package $TMP.
+- The class is public and final. It has a public constructor without parameters.
+- The class implements {{P}}IF_LOYALTY_RULES.
+- Do not add other public methods.
+
+# 5. Business rules
+Tier of a point value:
+1. A point value below zero counts as zero.
+2. 0 to 999 points is the basic tier.
+3. 1000 to 4999 points is the silver tier.
+4. 5000 to 19999 points is the gold tier.
+5. 20000 points and more is the platinum tier.
+
+Discount percent of a tier:
+6. basic is 0 percent.
+7. silver is 3 percent.
+8. gold is 7 percent.
+9. platinum is 12 percent.
+10. Any other tier value is 0 percent.
+
+Points to the next tier:
+11. A point value below zero counts as zero.
+12. basic needs 1000 points minus the point value.
+13. silver needs 5000 points minus the point value.
+14. gold needs 20000 points minus the point value.
+15. platinum needs 0 points.
+
+# 6. Constraints
+- Release target: 8.16.
+- Coding standards: Clean ABAP. Methods below 40 statements. No global variables.
+  No comment that restates the code.
+- Out of scope: do not change {{P}}IF_LOYALTY_RULES.
+
+# 7. Acceptance
+- The class is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.
