#
# 本地 CI 验证脚本 — 在 push 前模拟 GitHub Actions CI 全流程。
# 按照 .github/workflows/ci.yml 的 job 顺序依次执行，
# 在本地捕获绝大多数 CI 失败场景，避免 push 后才发现。
#
# 用法:
#   bash scripts/ci-local.sh          # 运行全部检查
#   bash scripts/ci-local.sh --quick  # 快速模式（跳过 e2e + docs）
#
# 退出码:
#   0 — 所有检查通过
#   1 — 存在失败项
#
# 对应 CI Jobs:
#   0. version-check     → bash scripts/check-version-sync.sh
#   1. lint-typecheck     → tsc --noEmit + npm run build
#   2. unit-tests         → vitest run test/unit
#   3. integration-tests  → npm run build + vitest run test/integration
#   4. e2e-tests          → vitest run test/e2e
#   5. format-check       → npm run format:check
#   6. docs-build         → cd website && npm run build
#
