[Feature Request] Add Eclipse version compatibility CI workflow

[unknowIfGuestInDream]

Describe the feature

参考实现
tlcsdm/eclipse-openexplorer#27

Adds a CI matrix build to verify the plugin compiles against multiple Eclipse release target platforms (2024-06 through 2026-03), parameterized via Maven properties so the same code can be validated against any target without modifying source files.

• targets/ — 8 target platform files (2024-06, 2024-09, 2024-12, 2025-03, 2025-06, 2025-09, 2025-12, 2026-03), each pointing at https://mirrors.aliyun.com/eclipse/releases/<version>/.
• target-platform.target — default baseline target that includes targets/2024-06.target via <location type="Target" uri="file:${project_loc:/com.tlcsdm.eclipse.openexplorer}/../../targets/2024-06.target"/>, so the baseline definition lives in a single source of truth.
• pom.xml — introduces:
  • target.platform.file consumed by target-platform-configuration as <file>../../${target.platform.file}</file>, defaulting to target-platform.target.
  • target.resolve.with.ee.constraints consumed by target-platform-configuration as <resolveWithExecutionEnvironmentConstraints>${target.resolve.with.ee.constraints}</resolveWithExecutionEnvironmentConstraints>, defaulting to true.
• compatibility.yml — workflow Maven invocation now:
  • quotes -Dtarget.platform.file=... to avoid Windows PowerShell argument splitting errors.
  • sets -Dtarget.resolve.with.ee.constraints per matrix target (true for 2024-* and false for 2025-03+), so newer Eclipse targets that require JavaSE-21 can still be resolved in compatibility checks while preserving strict EE-constrained behavior for baseline targets.

新增的target文件中引用的依赖与当前项目的target-platform.target 一致
