nyash-codex 4169da8c33 docs: Phase 131 refactoring tasks 1-7 completion
Update documentation with refactoring results:

**phase-131/README.md**:
- Document all 7 refactoring tasks (1: MergeContracts, 2: instruction_rewriter boxification,
  3-4: OutputContract + require_joinir_dev, 5: env.sh SSOT, 6: MergeConfig, 7: contract_checks tests)
- Add task descriptions and success criteria
- Document benefits and test results
- Reference implementation files and commits

**tools/build_llvm.sh**:
- Use TARGET_TMPDIR from env.sh for TMPDIR configuration
- Improve EXDEV mitigation for WSL compatibility
- Better artifact finalization handling

**Summary of Phase 131 Refactoring**:

7 refactoring tasks completed on schedule:
 Task 1 (MergeContracts): +30 lines, SSOT for merge contracts
 Task 2 (instruction_rewriter): +212 lines (policy box), -50 lines (rewriter)
 Task 3 (OutputContract): +90 lines, unified verification interface
 Task 4 (require_joinir_dev): +14 lines, dev-only helper
 Task 5 (env.sh SSOT): +1014 lines, centralized environment
 Task 6 (MergeConfig): +54 lines, unified configuration
 Task 7 (contract_checks tests): +116 lines, 4 new tests

Total: ~2500 new lines, 0 regressions, all tests PASS

Benefits:
- Code organization: Single responsibility principle
- Maintainability: SSOT reduces duplication
- Testability: Policy boxes and unit tests enable regression detection
- Developer experience: Clearer code, better documentation
