SkyZeroZx 0d1acd0165 feat(forms): support signal-based schemas in validateStandardSchema
Allow `validateStandardSchema()` to consume a computed schema so
validation rules stay in sync when the schema changes over time.

This supports schemas stored in computed signals (e.g. zod schemas that
depend on input signals) and ensures the effective schema updates after
initialization instead of being captured once.

Leon Senft 9f99b14882 fix(forms): only touch visible, interactive fields on submit
Don't touch hidden, disabled, or readonly fields on submit, since they
don't contribute to form validity. This also prevents errors from
appearing immediately if they're later made interactive.

Leon Senft 31e6f0d7dc test(forms): submit behavior while validation is pending
Ensure `submit()` behaves as expected while a form is pending.

- Submission is not blocked by pending validation.
- Submission errors prevent pending validation errors from appearing
  after they resolve on the same field.
- Submission errors don't prevent pending validation errors from
  appearing after they resolve on subfields.

Miles Malerba d89a80a970 feat(forms): Ability to manually register a form field binding in signal forms
This PR adds the ability to manually register a binding with the

automatic binding from `FormUiControl`.

Add comprehensive test cases to validate behavior when multiple

Miles Malerba 29f074a93f fix(forms): Rename signal form [field] to [formField]
This completes the rename started in #66136. `[field]` is too generic of

collisions with existing components. Therefore it is being renamed to
`[formField]`

Leon Senft c149f47ef6 refactor(forms): bind field properties to all directives on native controls
Since the `Field` directive manages binding `FieldState` properties to
the underlying form control automatically, the type checker prohibits
explicit bindings to the same properties to avoid conflicts. This proved
problematic in cases where developers wanted to bind these properties to
the inputs of other directives on form controls. Now the framework will
bind the field state properties to all matching directive inputs on
native controls.

Leon Senft cb09fb8308 fix(forms): support custom controls with non signal-based models
* Recognize directives with non signal-based models as valid custom controls
* Relax type checker to allow non signal-based models

The `FormValueControl` and `FormCheckboxControl` interfaces still
require a `model()`-input, however, a custom control need not implement
either interface to be bound by the `Field` directive.

All of the following examples can be used to define a custom control:

```ts
// Preferred: model()
class MyFormControl implements FormValueControl<string> {
  readonly value: model.required<string>();
}

// Supported: input() + output()
class MyFormControl {
  readonly value: input.required<string>();
  readonly valueChange: output<string>();
}

// Supported: @Input() + @Output()
class MyFormControl {
  @Input({required: true}) value!: string;
  @Output() valueChange: new EventEmitter<string>();
}
```

The latter two may still choose to implement `FormUiControl` for other
properties, but again it is not required.

Miles Malerba 348f149e8b feat(forms): pass field directive to class config
Updates signal forms to pass the full `Field` directive to the class
configuration functions, rather than just the state. This allows
developers to take the element as well as the state into consideration
when deciding classes to apply.

Closes #65762

BREAKING CHANGE: The shape of `SignalFormsConfig.classes` has changed

Previously each function in the `classes` map took a `FieldState`. Now
it takes a `Field` directive.

For example if you previously had:
```
provideSignalFormsConfig({
  classes: {
    'my-valid': (state) => state.valid()
  }
})
```

You would need to update to:
```
provideSignalFormsConfig({
  classes: {
    'my-valid': ({state}) => state().valid()
  }
})
```

Miles Malerba ebc5c2b083 feat(forms): redo the signal forms metadata API
This PR makes a number of changes to the metadata API to address design
flaws in the previous API. Some of the changes include:

- Replaces the previous `MetadataKey` and `AggregateMetadataKey` with a
  single unified `MetadataKey` that is used for all metadata.
- The new `MetadataKey` is only defined for fields that explicitly set
  it in their schema logic
- All metadata now has reducer / aggregate behavior
- The new `MetadataKey` has an option to create a managed key which
  wraps the result of its computed aggregate into some other structure
  such as a `Resource` or `linkedSignal`
- There are now two APIs to create metadata keys
  - `createMetadataKey` for pure computed metadata
  - `createManagedMetadataKey` for metadata that manages its computation
    internally

Alex Rickabaugh b96f65a963 fix(forms): memoize reads of child fields in signal forms (#65802)
Previously, navigating a `FieldTree` in signal forms involved reactive reads
of the value of the parent field(s), both directly and via `.childrenMap()`.

This meant that on _any_ change to the value of a field, reactive
notifications would trigger updates of computeds, reruns of effects, etc.
So for example, this effect would run on every change to the form:

```ts
const f = form(signal({data: 'abc', unrelated: 0}));
effect(() => {
  // accessing f.data incurs a dependency on f().value() which changes
  // on every change in the whole form
  console.log(f.data().value());
});
```

This is deeply counterintuitive and troublesome when attempting to write
effect logic, and also results in `computed`s unnecessarily updating.

This change introduces the concept of a "reader" computed, which memoizes
the access of a field at a given key via the reactive graph. With this, the
same `f.data` access above now depends on the `data` reader in `f` only,
which is effectively a constant computed. As a result, the effect only
reruns on changes to `data`'s value, as intended.
