With the deprecation of the configurable errorHandler in the Router, there is a missing
use-case to prevent the navigation promise from rejecting on an error. This rejection
results in unhandled promise rejections. This commit allows developers to instruct
the router to instead resolve the navigation promise with 'false', which matches
the behavior of other failed navigations.
Resolving the Promise would be the ideal default behavior. It is rare
that any code handles the navigation Promise at all and even more rare
that the Promise rejection is caught. Updating the default value for
this option should be considered for an upcoming major version.

Currently we generate the following TCB for a `@for` loop:
```ts
// @for (item of items; track item) {...}
for (const item of this.items) {
var _t1 = item;
// Do things with `_t1`
}
```
This is problematic if the item name is the same as a global variable (e.g. `document`), because when the TCB has references to that variable (e.g. `document.createElement`), it'll find the loop initializer instead of the global variable.
These changes fix the issue by generating the following instead:
```ts
for (const _t1 of this.items) {
// Do things with `_t1`
}
```
Fixes#53293.

In certain cases Angular hydration logic can not rely on the order in which elements are present in a template (for example, in content-projection use-cases) and there is a need to serialize a path from one node to another, so that hydration can locate an element on a page. The logic attempts to use an immediate parent element as an anchor and compute the path from it. If it fails - the path is computed starting from the <body> (this is a fallback).
This commit updates the logic to walk up the parents tree if an immediate parent (from a template) is disconnected from the DOM. This helps to shorten the lookup path and make it more stable.

In some injectors, there are LOTS of providers, making it slightly inconvenient to search for a certain one. This commit introduces a search-by-token for providers of a specific injector.

Currently, the link to an error guide is only included into an error message in dev mode. This change makes the `Find more at https://angular.io/errors/NG0XYZ` appear in the error message even in prod mode. Note: the rest of the error message is still tree-shaken away in prod mode (as it happens today).

This setting was added to prevent comment duplication, since the TS AST printer includes prior line comments as part of a given line with no way to really avoid that.
However in component imports, it is not safe to remove comments as they could be load bearing for some.

This commit fixes a memory leak where signal consumers would not be cleaned up for
descendant views when a view is destroyed, because the cleanup logic was only invoked
for the view that is itself being destroyed.

Previously we recorded separate param values for a strucural directive
and the element tag it goes on. We then later attempted to combine those
into a single value. However in some cases this merging logic matched
the directive with the wrong tag.
This change implements an alternate approach where we match the
directive to its element tag from the start, while we're traversing the
ops. This should be a more robust solution.

It is possible for ICUs to be nested inside other ICUs. This change
adjusts our ingestion logic to create extra interpolation ops for the
nested ICUs during ingestion.

We previously had an assertion that every placeholder in the i18n AST
had a corresponding param in the output. However, there are some cases
such as interpolations nested inside ICUs where this assertion is not
true. This change simply removes the asserion.

ICUs may share a placeholder, and in that case they need special
post-processing. This change adds logic to cover this possibility. In
particular, we set the param to a special placeholder value and then
pass an array containing the sub-message variables as a post-processing
param.

When we re-assign the slot dependencies for the i18nExprs, we should

This commit fixes an issue where swapping hydrated views was not possible in the new control flow repeater. The problem was caused by the fact that an internal representation of a view had no indication that hydration is completed and further detaching/attaching should work in a regular (non-hydration) mode. This commit adds a logic that resets a pointer to a dehydrated content and we use this as an indication that the view is swtiched to a regular mode.
Resolves#53163.

When the AOT compiler creates a delegated host for a provided TypeScript CompilerHost,
it delegates functionality back to the original via a series of internal method delegations.
However, unlike other members of the CompilerHost, `jsDocParsingMode` is not a method
and cannot be delegated in this way. Attempting to call bind on the property will result
in a runtime error. Instead, `jsDocParsingMode` is now delegated via get/set accessors.
Additionally, the override of `getSourceFile` now has an updated type signature to reflect
the additional of the `jsDocParsingMode` option for the method.
This is a followup to #53126 which updates the other DelegatingCompilerHost.
