chore: v2.2.73 — ASTRA-DEBUG 로그 레벨 + webview CSP font-src 보강

- ASTRA-DEBUG 정상 흐름 로그를 console.error → logInfo/console.log 로 강등
  (chatHandlers, extension, slashRouter): DevTools에 ERR로 찍히던 오탐 제거
- sidebar webview에 명시적 CSP meta 추가 + font-src에 data: 허용
  (sidebar.html, sidebarProvider._getHtml): VS Code outer iframe이 codicon.ttf를
  data:font/ttf 로 inject하면서 기본 CSP에 막혀 매 prompt 마다 violation
  경고가 찍히던 문제 해소
- 누적된 LM Studio / agent / 컨텍스트 매니저 / 테스트 갱신 동반
