## Summary
Delete an unused duplicate libc_util.py file. The active version is at
`invokeai/backend/model_manager/libc_util.py`
## QA Instructions
I ran a smoke test to confirm that memory snapshotting still works.
## Merge Plan

## Summary
This PR migrates all relative imports to absolute imports, and adds a
ruff check to enforce this going forward.
The justification for this change is here:
https://github.com/invoke-ai/InvokeAI/issues/6575
## QA Instructions
Smoke test all common workflows. Most of the relative -> absolute
conversions could be completed automatically, so the risk is relatively
low.
## Merge Plan
As with any far-reaching change like this, it is likely to cause some
merge conflicts with some in-flight branches. Unfortunately, there's no
way around this, but let me know if you can think of in-flight work that
will be significantly disrupted by this.

## Summary
This PR fixes a regression that caused the following models to be
treated as having size 0 in the model cache: `(TextualInversionModelRaw,
IPAdapter, LoRAModelRaw)`.
Changes:
- Call the correct model size calculation for all supported model types.
- Log an error message if an unexpected model type is loaded, to prevent
similar regressions in the future.
## QA Instructions
I tested the following features and verified that no models fell back to
using a size of 0 unexpectedly:
- Test-to-image
- Textual Inversion
- LoRA
- IP-Adapter
- ControlNet
(All tested with both SD1.5 and SDXL.)
I compared the model cache switching behavior before and after this
change with a large number of LoRAs (10). Since LoRAs are small compared
to the main models, the changes in behaviour are minimal. Nonetheless,
it makes sense to get this in for correctness. And it might make a
difference for some usage patterns with limited RAM.

- For single image deletion, select the image in the same slot as the deleted image
- For multiple image deletion, empty selection
- On list images, if no images are currently selected, select the first image
## Summary
- This PR exposes a `tile_size` field on `ImageToLatentsInvocation` and
`LatentsToImageInvocation`.
- Setting `tile_size = 0` preserves the default behaviour.
- This feature is primarily intended to support upscaling workflows that
require VAE encoding/decoding high resolution images. In the future, we
may want to expose the tile size as a global application config, but
that's a separate conversation.
- As a general rule, larger tile sizes produce better results at the
cost of higher memory usage.

The selection logic is a bit complicated. We have image selection and pagination, both of which can be triggered using the mouse or hotkeys. We have viewer image selection and comparison image selection, which is determined by the alt key.
This change ties the room together with these behaviours:
- Changing the page using pagination buttons never changes the selection.
- Changing the selected image using arrows may change the page, if the arrow key pressed would select an image off the current page.
- `right` on the last image of the current page goes to the next page
- `down` on the last row of images goes to the next page
- `left` on the first image of the current page goes to the previous page
- `up` on the first row of images goes to the previous page
- If `alt` is held when using arrow keys, we change the page, but we only change the comparison image selection.
- When using arrow keys, if the page has changed since the last image was selected, the selection is reset to the first image on the page.
- The next/previous buttons on the image viewer do the same thing as `left` and `right` without `alt`.
- When clicking an image in the gallery:
- If no modifier keys are held, the image is exclusively selected.
- If `ctrl` or `meta` are held, the image's selection status is toggled.
- If `shift` is held, all images from the last-selected image to the image are selected. If there are no images on the current page, the selection is unchanged.
- If `alt` is held, the image is set as the compare image.
- `ctrl+a` and `meta+a` add the current page to the selection.
The logic for gallery navigation and selection is now pretty hairy. It's spread across 3 hooks, a listener, redux slice, components.
When we next make changes to this part of the app, we should consider consolidating some of the related logic. Probably most of it can go into a single listener and make it much simpler to grok.
Don't like this UI (even though I suggested it). No need to prevent the user from interacting with the search term field during fetching. Let's figure out a nicer way to present this in a followup.
