AX Agent 구형 설정창의 PlanMode dead UI를 제거

- AgentSettingsWindow에서 계획 모드와 Plan Mode 도구 UI 및 save/load/event 코드 제거

- clean 파일 기준 검색상 남은 PlanMode 참조를 JSON 호환용 AppSettings와 SubAgentTool 안전 고정 경로로 축소

- README와 DEVELOPMENT 문서에 2026-04-05 21:20 (KST) 기준 변경 내역과 parity 99% 재평가 반영

- 검증: dotnet build src/AxCopilot/AxCopilot.csproj -c Release -v minimal -p:OutputPath=bin\\verify\\ -p:IntermediateOutputPath=obj\\verify\\ (경고 0 / 오류 0)
