Currently circular references in user code manifest themselves with an error like `Cannot read properties of undefined (reading 'ɵcmp')`. This is a bit cryptic so these changes add an assertion mentioning circular references.
Relates to #65917.

Prevents the deprecation warning that was incorrectly triggered when
defining an InjectionToken with only a `factory`, which correctly
defaults to the `root` scope.

We recently allowed users to have a dynamic input `type` with signal forms, but the logic that infers the value type falls back to `string` even though in theory it can be any of the other types.
These changes expand the inferred type to `string | number | boolean | Date | null` if we detect a dynamic `type` binding.

Wrap operationsCounter method calls (recordCreate, recordDestroy, reset)
with ngDevMode guards to ensure they are tree-shaken in production builds.
This aligns with the existing pattern where operationsCounter is only
initialized in development mode, and eliminates unnecessary method call
overhead in production.
The optional chaining (?.) is retained as TypeScript doesn't narrow types
based on ngDevMode checks, but the entire expression will be removed during
production builds.

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

FormUiControl states that hidden, pending and dirty will be bind in custom controls, but this is currently not the case.

This change replaces all remaining occurrences of `typeof ngDevMode !== undefined`
with the correct `typeof ngDevMode !== 'undefined'` form. This aligns the codebase
with JavaScript typeof semantics and maintains consistency with other Angular code.

Replace the 'any' type with ClassDebugInfo for the debugInfo parameter in
stringifyTypeFromDebugInfo function. This removes the TODO comment that was
tracking the need for proper typing without creating circular dependencies.
The change improves type safety while avoiding circular imports since
stringify_utils.ts doesn't export anything that definition.ts imports.

- Use getComponentDef in debugStringifyTypeForError to clean up TODO

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.

Previously, several values were being passed into the creation of
`FieldNodeStructure`s that were only used in the creation of child nodes.
Separately, we also passed a `createChildNode` function which these values
were passed back into.
Instead, this moves the small bit of logic from structure.ts behind the
`createChildNode` callback, which reduces the passing of values back-and-
forth and gives `createChildNode` a much more suitable signature.

Move the instructions used to dynamically bind a `Field` directive to a
form control onto the `Field` itself. This way the instructions are only
retained if the app uses the `Field` directive.

When registering providers, the DI system assumes that `viewProviders` are registered before plain `providers`. This was reinforced by components always being first in the array of directive matches, only one component being allowed per node and the fact that only components can have `viewProviders`.
This breaks down if there are host directives with `providers` on the component, because they'll execute earlier, throwing off the order of operations.
These changes fix the issue by separating out the resolvers for `viewProviders` and plain `providers` and explicitly running the component's `viewProviders` resolver before any others. This also has the benefit of not attempting to resolve `viewProviders` for directives which are guaranteed not to have them.
Fixes#65724.

Previously, the XSRF interceptor only added the XSRF token to requests with relative URLs.
This commit updates the interceptor to also add the token to requests with absolute URLs, provided they match the current origin.

This commit adds a `.catch()` handler to `transition.finished` from `document.startViewTransition` to prevent unhandled promise rejections. The finished promise can reject with `TimeoutError` or `InvalidStateError` when transitions fail during or after the animation phase.
Based on the Blink source code, the `finished` promise can reject with:
* `TimeoutError`: "Transition was aborted because of timeout in DOM update"
* `InvalidStateError`: "Transition was aborted because of invalid state"
This may happen when the DOM update phase exceeds the browser's internal timeout threshold.

The end of the Router navigation is a block of synchronous logic that
can be compressed into a single operator rather than splitting it across
several, making it harder to step through. The only benefit from the
split is automatic unsubscribe/cancellation, which we can replicate
with an additional 'shouldContinue' check before proceeding.

Currently when the signal debug name transform sees something like `const foo = signal(0);`, it transforms the signal into `signal(0, {...(ngDevMode ? { debugName: 'foo' } : {})})`. After minification this becomes `signal(0, {})` which will allocate memory for the empty object literal.
These changes rework the logic to produce `signal(0, ...(ngDevMode ? [{ debugName: 'foo' }] : []))` which will be fully tree shaken away to `signal(0)`.

In the case that a component injector is destroyed before the animation
queue runs, the animation queue would fail to run because it was using a
destroyed injector. This commit changes the animation queue to run in the
context of the EnvironmentInjector, which is not destroyed until the app
is destroyed.
