We've long suspected there is a memory leak in Invoke, but that may not be true. What looks like a memory leak may in fact be the expected behaviour for our allocation patterns.
We observe ~20 to ~30 MB increase in memory usage per session executed. I did some prolonged tests, where I measured the process's RSS in bytes while doing 200 SDXL generations. I found that it eventually leveled off at around 100 generations, at which point memory usage had climbed by ~900MB from its starting point.
I used tracemalloc to diff the allocations of single session executions and found that we are allocating ~20MB or so per session in `ModelPatcher.apply_ti()`.
In `ModelPatcher.apply_ti()` we add tokens to the tokenizer when handling TIs. The added tokens should be scoped to only the current invocation, but there is no simple way to remove the tokens afterwards.
As a workaround for this, we clone the tokenizer, add the TI tokens to the clone, and use the clone to when running compel. Afterwards, this cloned tokenizer is discarded.
The tokenizer uses ~20MB of memory, and it has referrers/referents to other compel stuff. This is what is causing the observed increases in memory per session!
We'd expect these objects to be GC'd but python doesn't do it immediately. After creating the cond tensors, we quickly move on to denoising. So there isn't any time for the GC to happen to free up its existing memory arenas/blocks to reuse them. Instead, python needs to request more memory from the OS.
We can improve the situation by immediately calling `del` on the tokenizer clone and related objects. In fact, we already had some code in the compel nodes to `del` some of these objects, but not all.
Adding the `del`s vastly improves things. We hit peak RSS in half the sessions (~50 or less) and it's now ~100MB more than starting value. There is still a gradual increase in memory usage until we level off.
* build: prevent `opencv-python` from being installed
Fixes this error: `AttributeError: module 'cv2.ximgproc' has no attribute 'thinning'`
`opencv-contrib-python` supersedes `opencv-python`, providing the same API + additional features. The two packages should not be installed at the same time to avoid conflicts and/or errors.
The `invisible-watermark` package requires `opencv-python`, but we require the contrib variant.
This change updates `pyproject.toml` to prevent `opencv-python` from ever being installed using a `uv` features called dependency overrides.

When a layer is initialized, we do not yet know its bbox, so we cannot fit the stage view to the layer. We have to wait for the bbox calculation to finish. Previously, we had no way to wait unti lthat bbox calculation was complete to take an action.
For example, this means we could not fit the layers to the stage immediately after creating a new layer, bc we don't know the dimensions of the layer yet.
This callback lets us do that. When creating a new canvas from an image, we now...
- Register a bbox update callback to fit the layers to stage
- Layer is created
- Canvas initializes the layer's entity adapter module (layer's width and height are set to zero at this point)
- Canvas calculates the bbox
- Bbox is updated (width and height are now correct)
- Callback is ran, fitting layer to stage
Also change import order to ensure CLI args are handled correctly. Had to do this bc importing `InvocationRegistry` before parsing args resulted in the `--root` CLI arg being ignored.
