v6.4.0

This release includes a handful of fixes and enhancements. 

## Enhancements

Shout-out to @csehatt741 for knocking out some great QoL improvements. Thank you!

- Canvas Bbox visibility can be toggled with `shift+o`. Thanks @csehatt741!
- Nodes with execution errors are highlighted red. Thanks @csehatt741!
- Prevent a field from being added to Workflow Builder forms multiple times. Thanks @csehatt741!
- Support recall of CLIP Skip metadata. Thanks @csehatt741!
- Fixed some issues with model install paths.
- Tweaked state persistence strategy - now debounced to 300ms instead of throttled to 2000ms. This should reduce stutters while doing things like panning around the Canvas.
- SDXL Style prompts have been removed from the Generate, Canvas and Upscaling tabs. This rarely-used setting was unintuitive at best. You can still use it in Workflows, but we are removing this footgun from the linear UI tabs.
- Prompt and seed metadata may now be recalled on the Upscaling tab.
- The buttons to download potentially very large starter model bundles show a confirmation dialog before starting the download. Thanks @csehatt741!
- Merged layers are inserted in the right spot in the layers panel. Thanks @csehatt741!
- Added button to image context menu and viewer toolbar to locate an image in the gallery. The image's board is selected and image scrolled to. Thanks @csehatt741!
- Support FLUX PEFT LoRAs with `base_model.model` key prefix.
- Improved VAE encode VRAM usage.
- Updated translations. Thanks @Harvester62!

## Fixes

- Minor bug when concatenating Kontext ref images in latent space that could result in some images not being "seen".
- Fit to Bbox functionality could result in the layer being sized correctly but positioned incorrectly when the bbox was not aligned to the 64px grid.
- Allow use of mouse in node title editable inputs.

## Internal/Dev

- Fix AMD docker image build issue related to disk space. Thanks @heathen711!

## Installing and Updating

**The Invoke Launcher is the recommended way to install, update and run Invoke**. It takes care of a lot of details for you - like installing the right version of python - and runs Invoke as a desktop application.

Note: With recent updates to `torch`, users on older GPUs (20xx and 10xx series) will likely run into issues with installing/updating. We are still evaluating how we can support older GPUs, but in the meantime users have found success manually downgrading `torch`. Head over to [discord](https://discord.gg/ZmtBAhwWhy) if you need help.

Follow the [Quick Start guide](https://invoke-ai.github.io/InvokeAI/installation/quick_start/) to get started with the launcher.

If you don't want to use the launcher, or need a headless install, you can follow the [manual install guide](https://invoke-ai.github.io/InvokeAI/installation/manual/).
