chore: initial commit — portable agent memory & skill scaffold

Extracted and cleaned up from a prior WSL/Windows agent-memory setup.
Contains only project-agnostic content:

- Claude_Memory/: feedback rules, user profile, reusable reference docs,
  session scratch space (claude_info/, claude_log/), mirrored skill defs
- caveman/: ultra-compressed communication mode skill + subcommands
- html-slide-deck/: self-contained HTML slide deck builder skill

Project-specific knowledge (previously mixed in) was moved out to each
project's own repository as part of this cleanup.

+description: Claude Code usage 리셋 알람 패턴 — 사용자가 usage 꽉 찼다고 하면 1시간 후 PushNotification 예약

+
+사용자 "usage 꽉 찼다"/"usage full" 전달 시:
+1. 즉시 `ScheduleWakeup(delaySeconds=18000)` 호출 — 5시간 후 예약
+2. 5시간 후 `PushNotification` 발송 — "Claude Code usage가 리셋됐을 것 같습니다"
+
+**Why:** Claude Code usage % 조회 API 없음 — 직접 감지 불가. 사용자 수동 알림 기준 5시간 타이머.
+
+**How to apply:** 사용자 usage 한도 도달 메시지 수신 즉시 — 확인 없이 ScheduleWakeup 실행.
