Vacuuming

https://github.com/MerginMaps/python-api-client/blob/master/mergin/utils.py#L99

Vacuuming could be useful even for gpkgs without the -wal sidecar

Vacuuming takes some time, so we should check that it is worth it.

When dropping a table, or removing records from tables, the space they occupied is not immediately released and kept in the pool of file pages that SQLite may reuse later. If you need to shrink the file to its minimum size, you need to issue an explicit "VACUUM" SQL request.

When content is deleted from an SQLite database, the content is not usually erased, but rather the space used to hold the content is marked as being available for reuse.

从 mergin/utils.py 第 99 行开始，阅读链接的 GDAL GeoPackage 和 SQLite VACUUM 指南。检查当前逻辑如何判断是否值得执行 VACUUM，包括没有 -wal 伴随文件的 GeoPackages。完成的标准是该判断涵盖这种情况，且不会进行不必要的 VACUUM；使用项目现有的测试进行验证。
