--dry-run and --pre-load still downloading assets

Not sure if this is a bug or expected behavior. When running my export with `--dry-run` and `--download-missing`, it seems to still download all the files (but doesn't export as it shouldn't). I would expect it not to download at all because it's supposed to be a dry run. Probably even worse is that this also happens with `--pre-load`. Here's what I did: 1. Copied data from an export I did a while back to a test folder 2. Ran `export` with `--pre-load` and `--download-missing` What I expected was that `osxphotos` would realize that all files are present (and also where they are supposed to be in the hierarchy) and simply update the `export.db` to match. Also, when run without `--download-missing` it would create `* (1).jpg.xmp` files next to the already existing `*.jpg.xmp` files. Only reason I can think of is that it recognizes it as 2 different files (original vs. thumbnail)?! I'm using the current latest version directly from `main` (`6cb2f92`) on macOS 26.2 with Photos running on "optimized storage". Is the "optimized" part already the problem?
