Vacuuming

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.

從 mergin/utils.py 第 99 行開始，閱讀連結的 GDAL GeoPackage 和 SQLite VACUUM 指南。檢查目前的邏輯如何判斷是否值得執行 VACUUM，包括沒有 -wal 伴隨檔案的 GeoPackages。完成的標準是該判斷涵蓋這種情況，且不會進行不必要的 VACUUM；使用專案現有的測試進行驗證。
