refactor(forms): hook up `formField` directive in compiler
Hooks up the `formField` direcive to get the same treatment as the
`field` directive in the compiler.

This commit updates the DOM security schema and sanitization logic to properly recognize and sanitize `href` and `xlink:href` attributes on SVG `<script>` elements.
Sets up the compliance tests to target es2022 since that's the default in the CLI. Also updates all of the tests, primarily because the generated output for static properties has changed.
PR #60455 improved error reporting for `@Component.imports` by scoping the diagnostic to an individual
element within the `imports` array, but this may introduce hard to track diagnostics when it ends
up being reported (far) away from the component itself.
This can be even more problematic when the diagnostic would end up being reported in a declaration file,
as happened in issue #65686; the declaration files of an imported library contained syntax that the
static interpreter did not support, hence the `@Component.imports` was rejected with a diagnostic reported
in the library's declaration file. This diagnostic isn't guaranteed to be reported (e.g. the CLI only
gathers Angular-specific diagnostics for Angular-compiled files, which excludes declaration files).
This commit changes the diagnostic location to ensure it is being reported within the `@Component.imports`
expression, in most cases retaining the desirable effect of #60455 while avoiding out-of-band diagnostics.
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.
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)`.
This is necessary to exclude a race condition where the MutationObserver initialized by the instruction fired before the inputs are binded.

This commit implements a security fix to prevent XSS vulnerabilities where SVG animation elements (`<animate>`, `<set>`, etc.) could be used to modify the `href` or `xlink:href` attributes of other elements to `javascript:` URLs.
Escape @-prefixed template control flow constructs during doc extraction so JSDoc parsing keeps description text intact. Add regression coverage for @for snippets.
Currently when we detect a `field` binding on a native element, we treat it as a built-in native control. This might not be the case if it's a pre-existing `ControlValueAccessor` relying on the CVA interop.
These changes try to detect any CVA-like directive on the element and disable the additional type checking if there are any.
Fixes#65468.
Reworks the way we approach type checking of signal forms to be closer to the behavior at runtime. There are a couple of scenarios that we handle:
1. For native controls, we now produce simplified type checking code that looks as follows:
```
var t1 = null! as number | string; // Type depends on the input `type`.
t1 = someField().value();
```
2. For custom controls we generate bindings to the individual inputs, rather than checking conformance against `FormValueControl`/`FormCheckboxControl`. This is closer to the behavior at runtime and it allows us to handle generic directives properly.
Adds some logic that won't report the `value` or `checked` inputs as missing when the `Field` directive is present since it will bind to the inputs implicitly.
Switches to checking against `FormValueControl<any>` instead of `FormValueControl<unknown>` when checking whether custom controls conform to the interface.
Fixes#64946.
By intersecting with `object` instead of `unknown` in the primitive and
`FormControl` cases, we get TypeScript to show nicer type errors that
mention `FieldTree<...>` insetad of `() => FieldState<...>`
For each field state property, check if it has changed since the last
time it was checked before writing it the corresponding form control
property.
The `pattern` and `required` properties of the field state now return a
default value rather than `undefined` if not defined by metadata.
This adds a new compilation error if someone attempts to put legacy animations and `animate.enter` or `animate.leave` in the same component.

Renames the control directive and the input that users set to bind a
field to a UI control.
Previously users would do:
```
<input [control]="someField">
```
Now users will do:
```
<input [filed]="someField">
```

Currently if `TestBed.overrideComponent` is used on a class that uses initializer APIs (e.g. `input()`), the initializer metadata will be wiped out, because `overrideComponent` re-compiles the class with the information set by `setClassMetadata`. `setClassMetadata` only captures decorated members at the moment.
These changes introduce some logic to capture the new initializer-based APIs in `setClassMetadata` as well.
Fixes#57944.

Move most of the implementation of the `Control` directive into core
framework instructions. This allows field state changes to be propagated
to their corresponding UI controls directly during execution of a
template update block, instead of relying on `effect()`s to synchronize
each change later during the update (and too late in the case of
required inputs).
* Define a private API in `@angular/core` for signal forms to implement:
* `ɵControl` for the `Control` directive.
* `ɵFieldState` for the control's associated `FieldState`.
* Emit specialized instructions when compiling a `[control]` binding:
* `ɵɵcontrolCreate` sets up the `ɵControl` directive if present,
determines whether it's bound to a native control element or a
custom control component, and adds the appropriate event listeners
to notify the `ɵFieldState` of UI changes.
* `ɵɵcontrol` propagates changes from `ɵFieldState` properties to their
corresponding UI control properties (in additional to binding the `control`
property itself).
PR Close#63773
* Emit a `ɵɵcontrol` instruction in place of `ɵɵproperty` for property
bindings named "control". This instruction cannot be chained, but is
otherwise functionally equivalent.
* Upcoming changes will use the `ɵɵcontrol` instruction to bind a signal
form field to a UI control (be it a native element or custom directive).

This commit updates the TypeScript configuration across the project to use `moduleResolution: "bundler"`. This modernizes our module resolution strategy to align with current TypeScript best practices and bundler behaviors.
The following changes are included:
- Updated `tsconfig.json` files to set `moduleResolution` to `"bundler"`.
- Updated the `rules_angular` bazel dependency to a version compatible with these changes.
- Adjusted related test files and golden files to reflect the new module resolution strategy.

Fixes an error where using an alias in a defer block caused the compiler CLI to fail when parsing. The resolution logic in ComponentDecoratorHandler was updated to correctly handle deferred dependencies with aliased imports.
