build: Complete Spring Boot 3 migration: update dependencies, fix deprecated APIs, and add packaging workflow

[Copilot]

Finishes the Spring Boot 3 migration by addressing remaining dependency and API issues, and adds a manual packaging workflow.

Proposed Changes

1. Remove log4j2.version override — The pinned 2.17.0 (a Log4Shell-era workaround) was downgrading from SB3's managed 2.23.1. Removed to use the managed version.
2. Update MySQL connector — mysql:mysql-connector-java:5.1.49 → com.mysql:mysql-connector-j (SB3-managed 8.3.0). Old coordinates and 5.1.x are deprecated.
3. Update git-commit-id plugin — pl.project13.maven:git-commit-id-plugin → io.github.git-commit-id:git-commit-id-maven-plugin. Old groupId is deprecated; SB3 uses the new coordinates.
4. Replace deprecated ListenableFuture in VisibleThreadPoolTaskExecutor — submitListenable() → submitCompletable(), removed deprecated execute(Runnable, long) override. These were deprecated in Spring Framework 6.
5. Add manual packaging workflow — New .github/workflows/package.yml triggered only via workflow_dispatch. Builds with mvn package, uploads genCode.jar as an artifact with 1-day retention.

PR Summary

• New GitHub Actions Workflow for Project Packaging
  The team has integrated a new automated process for compiling and preparing the project for distribution. This updated process uses the latest Java Development Kit (JDK 17) and Maven, a project management tool, to build the project while skipping tests for efficient packaging.

• Update in Database Connector and General Dependency Updates
  The outdated MySQL database connector in the project setup file (pom.xml) has been replaced with a more current version (mysql-connector-j). Additionally, a dependency associated with documenting Git commits within the project has been modernized.

• Code Refactoring and Modernization
  The module VisibleThreadPoolTaskExecutor.java has undergone improvements and clean-ups. A deprecated method has been removed to avoid potential issues in the future owing to lack of support. The functionality to send multiple asynchronous tasks (submitListenable methods) now returns CompletableFuture, a feature of Java's API that allows for more flexible and powerful handling of tasks running concurrently. This improves the performance and reliability of the application.

@copilot mysql-connector-j 和 git-commit-id-maven-plugin 没定义版本号，怎么编译过？

@copilot mysql-connector-j 和 git-commit-id-maven-plugin 没定义版本号，怎么编译过？

这两个的版本由 spring-boot-starter-parent:3.3.5 的 dependency management 和 plugin management 统一管理，不需要显式定义版本号。实际解析的版本为：

• com.mysql:mysql-connector-j → 8.3.0
• io.github.git-commit-id:git-commit-id-maven-plugin → 8.0.2

这也是 Spring Boot 推荐的用法——对于其管理范围内的依赖和插件，省略版本号可以确保与 Spring Boot 版本的兼容性。
