does zipseq currently scan other types in the seq than png? e.g. jpg, exr

Checking which file types `zipseq` scans:

Yes. `zipseq` scans multiple file types, not just PNG.
```45:52:zip_sequences.py
SEQUENCE_EXTENSIONS = {
".png",
".jpg",
".jpeg",
".tif",
".tiff",
".exr",
}
```
The `find_sequence_dirs()` function uses this set to identify sequence directories:
```491:491:zip_sequences.py
has_frames = any(Path(dirpath, f).suffix.lower() in SEQUENCE_EXTENSIONS for f in filenames)
```
Supported extensions:
- `.png`
- `.jpg`
- `.jpeg`
- `.tif`
- `.tiff`
- `.exr`
All of these are included in archives and tracked in manifests.

_**User (2025-12-29 17:37Z)**_
if there's a sequence with both jpg and png (by mistake) will it scan and compress both?
---
_**Agent (model default, mode Agent)**_
---
Yes. If a sequence directory contains both JPG and PNG files, both will be scanned and compressed.
How it works:
1. `find_sequence_dirs()` checks if a directory has any files matching `SEQUENCE_EXTENSIONS` (`.png`, `.jpg`, `.jpeg`, `.tif`, `.tiff`, `.exr`). If it finds any, it treats the directory as a sequence directory.
2. Once identified as a sequence directory, `iter_sequence_files()` includes all files in that directory (except `Thumbs.db` and archive paths), regardless of extension:
```517:524:zip_sequences.py
def iter_sequence_files(seq_dir: Path) -> Iterator[Path]:
for dirpath, dirnames, filenames in os.walk(seq_dir):
path = Path(dirpath)
dirnames[:] = [d for d in dirnames if d not in ("_archive", "_CURRENT")]
if is_archive_path(path):
continue
for filename in filenames:
# Ignore Thumbs.db files completely
if filename.lower() == "thumbs.db":
continue
yield path / filename
```
So if a directory has both `frame_001.jpg` and `frame_001.png`, both will be:
- Included in the state manifest
- Compressed into the archive
The extension check only determines whether a directory is a sequence directory; it doesn't filter which files get included once it's identified as one.

I had one with jpgs that I removed so only the pngs remain, but the manifest isn't changing.

Checking the state comparison logic to see why the manifest isn't updating after removing JPGs:

The quick-skip optimization is likely the cause. It skips state computation if the directory mtime is <= the archive mtime, which can miss deletions when the directory mtime doesn't update. Checking the logic and making it more reliable:

The quick-skip optimization can miss file deletions when the directory mtime doesn't update. Adding a pre-check: if any files from the stored state are missing, we'll recompute the state instead of skipping.

Fixed the issue. The quick-skip optimization was skipping state computation when the directory mtime was <= the archive mtime, which can miss file deletions if the directory mtime doesn't update.
**The fix:** Before the quick-skip, the code now verifies that all files in the stored state still exist. If any are missing (like the JPGs you removed), it skips the quick-skip and recomputes the full state, which will detect the change and update the manifest.
Now when you run `zipseq`:
1. It checks if stored files still exist
2. If JPGs are missing, it recomputes the state
3. It detects the difference and updates the manifest
4. It recompresses the archive with only the remaining PNGs
The manifest should now update correctly when files are removed, even if the directory mtime doesn't change.
