…efs #296 Add `parsec self-update` subcommand that queries the GitHub releases API, compares the running version against the latest published release, and prints a cargo-install upgrade command when a newer version is available. ## Changes - src/cli/commands/update.rs (new): async fetch + semver compare + output - src/cli/commands/mod.rs: wire update module - src/cli/mod.rs: SelfUpdate command variant + run dispatch ## Implementation detail - Uses reqwest (already a dep) with 8 s timeout and a parsec/VERSION User-Agent - Numeric semver comparison handles 0.10.0 > 0.9.0 correctly (7 unit tests) - Gracefully degrades on network error (prints current version + releases URL) - Respects global --offline flag: skips network call, prints version only - Phase 2 will add in-place binary replacement (see issue #296) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

무엇
parsec self-update새 서브커맨드 추가 — GitHub releases API 에서 최신 버전을 조회해 현재 버전과 비교하고, 업데이트가 있으면cargo install업그레이드 명령을 출력합니다.Refs #296
왜
parsec에는 자체 업데이트 확인 기능이 없어 사용자가 최신 버전 여부를 수동으로 확인해야 했습니다. Phase 1 은 알림까지, Phase 2 에서 바이너리 자동 교체를 구현합니다.변경

reqwest(기존 dep) — 8 초 타임아웃,parsec/VERSIONUser-Agent0.10.0 > 0.9.0정확히 처리 (문자열 비교 버그 없음)--offline글로벌 플래그 준수: 네트워크 스킵, 버전만 출력다음 Phase 힌트
Phase 2:
gh release download또는 HTTP 로 바이너리 다운로드 + 임시 파일 원자 교체 + checksum 검증리스크
low — 신규 독립 명령, 기존 코드 미변경, 새 외부 dep 없음, 네트워크 실패 graceful
롤백
브랜치 삭제로 완전 롤백 가능. 기존 명령 미영향.
