* feat(log-store): skip corrupted object store WAL segments per region A segment that does not decode, because its checksum does not match or its content disagrees with its footer entry, is fetched once more. If it still does not decode, the read follows `on_corrupted_segment`: `skip` records a WAL hole for the region with the object key, sequence and the footer's entry id range, increments `greptime_logstore_object_store_wal_skipped_segments_total`, logs a warning and continues with the next object; `fail` fails the read. A failed fetch fails the read in both modes. Holes are kept in memory per region and can be listed from the store. The standalone test builder allocates WAL options through `build_standalone_wal_provider`, and integration tests run a standalone instance on the object store WAL across restarts, on S3 when the `GT_S3_*` variables are set. The standalone shutdown runs every step and returns the first error. Signed-off-by: jeremyhi <fengjiachun@gmail.com> * test(cmd): cover the best-effort standalone stop Build a standalone instance whose leader services fail to stop and whose datanode servers fail afterwards, and check that `Instance::stop` still stops the object store WAL and returns the leader services error. Rename `skip_segment` to `record_skipped_segment` and the file store integration test to `test_standalone_object_store_wal_survives_restarts_on_file`.
