Major cleanup of RelatedModels.tsx for improved readability, structure, and maintainability.
Dried out repetitive logic
Consolidated model type sorting into reusable helpers
Added disallowed model type relationships to prevent broken connections (e.g. VAE ↔ LoRA)
- Aware this introduces a new constraint—open to feedback (see PR comment)
Some naming and types may still need refinement; happy to revisit
Adds full support for managing model-to-model relationships in the UI and backend.
Introduces RelatedModels subpanel for linking and unlinking models in model management.
- Adds REST API routes for adding, removing, and retrieving model relationships.
- New database migration: creates model_relationships table for bidirectional links.
- New service layer (model_relationships) for relationship management.
- Updated frontend: Related models float to top of LoRA/Main grouped model comboboxes for quick access.
- Added 'Show Only Related' toggle badge to MainModelPicker filter bar
**Amended commit to remove changes to ParamMainModelSelect.tsx and MainModelPicker.tsx to avoid conflict with upstream deletion/ rewrite**
## Summary
- Modify stats reset to be on a per session basis, rather than a "full
reset", to allow for parallel session execution
- Add "aider" to gitignore

When we do our field type overrides to allow invocations to be instantiated without all required fields, we were not modifying the annotation of the field but did set the default value of the field to `None`.
This results in an error when doing a ser/de round trip. Here's what we end up doing:
```py
from pydantic import BaseModel, Field
class MyModel(BaseModel):
foo: str = Field(default=None)
```
And here is a simple round-trip, which should not error but which does:
```py
MyModel(**MyModel().model_dump())
# ValidationError: 1 validation error for MyModel
# foo
# Input should be a valid string [type=string_type, input_value=None, input_type=NoneType]
# For further information visit https://errors.pydantic.dev/2.11/v/string_type
```
To fix this, we now check every incoming field and update its annotation to match its default value. In other words, when we override the default field value to `None`, we make its type annotation `<original type> | None`.
This prevents the error during deserialization.
This slightly alters the schema for all invocations and outputs - the values of all fields without default values are now typed as `<original type> | None`, reflecting the overrides.
This means the autogenerated types for fields have also changed for fields without defaults:
```ts
// Old
image?: components["schemas"]["ImageField"];
// New
image?: components["schemas"]["ImageField"] | null;
```
This does not break anything on the frontend.
* support for custom error toast components, starting with usage limit
* add support for all usage limits
