ci: CI 迁移至 GitHub Actions，接入 Codecov 覆盖率上传

- 新增 .github/workflows/ci.yml：JDK 17 编译 + travis profile 单元测试
  + jacoco 覆盖率上传 Codecov（CODECOV_TOKEN 使用仓库密钥），
  写法参考 https://github.com/codingapi/flow-engine/blob/main/.github/workflows/ci.yml
- 移除 .travis.yml（含明文 CODECOV_TOKEN，已轮换至 GitHub 仓库密钥）
- README 徽章：Travis CI 徽章替换为 GitHub Actions Build 徽章，
  Codecov 徽章指向 17.3.x 分支
