v2.6.0: Phase 3 + Phase 4 — accessibility + code sign infra

Phase 3 (also v2.5.0 in CHANGELOG):
- Weekly auto report on Monday
- Matplotlib chart hover annotation
- Clock-in time distribution histogram
- Leave usage calendar with color coding

Phase 4 (v2.6.0):
- Font scale 100/125/150% (instant apply)
- High-contrast mode (black bg + yellow text)
- Authenticode signing infra in release.ps1 (env-gated, optional)

+## [2.6.0] — 2026-04-30
+
+### Added — Phase 4 (3종)
+- **글꼴 크기 조절** (100% / 125% / 150%) — 설정에서 즉시 반영
+- **고대비 모드** — 검정 배경 + 노란 텍스트 (시각약자/야간)
+- **코드 서명 인프라** — `release.ps1`에 Authenticode 서명 단계 추가 (옵션)
+  - `$env:CODE_SIGN_CERT` (`.pfx` 경로) + `$env:CODE_SIGN_PASS` 환경변수 설정 시 자동 서명
+  - signtool.exe 없거나 cert 미설정 시 자동 스킵
+  - 코드 서명 인증서 확보 후 활성화하면 SmartScreen 경고 제거 가능
+
+### Settings (신규)
+- `font_scale`, `high_contrast`

 ## [2.5.0] — 2026-04-30
