The `base64-js` package was only used in tests that were run only on
Node.js. On Node.js, `Buffer` is available which can natively perform
base64 conversion. By using `Buffer in these Node.js only tests, the
`base64-js` package can be removed from the repository.

This change replaces the implementation of the multi-map used to store
detached views while reconciling lists. The new implementation optimizes
memory allocation for such map and avoid arrays allocation when there are
no duplicated keys.

The PR https://github.com/angular/angular/pull/52465 introduced short-circuit for
the signal equality invocation - with the reasoning that the equality function
should never return false for arguments with the same references. In practice it
turned out that it is rather surprising and the subsequent PR
https://github.com/angular/angular/pull/52532 added a warning when the short-circuit
was taking priority over the equality function.
Still, the presence of the short-circuit prevents people from mutating objects in
place and based on https://github.com/angular/angular/issues/52735 this is a common
and desired scenario. This change removes the short-circuit altogether and thus
fixes the mentioned issue.
We do recognize that removing short-circuit exposes developers to the potentially
surprising logic where mutated in-place change won't be propagated throug the
reactivity graph (due to the deault equality function). But we assume that this might
be less surprising / more desirable as compared to the short-circuit logic.

This change fixes and issue where the expectation was that change
detection always goes through `detectChangesInView`. In reality,
`detectChangesInternal` directly calls `refreshView`
and refreshes a view directly without checking if it was dirty (to my discontent).
This update changes the implementation of `detectChangesInternal` to
actually be "detect changes" not "force refresh of root view and detect
changes". In addition, it adds the refresh flag to APIs that were
previously calling `detectChangesInternal` so we get the same behavior
as before (host view is forced to refresh).
Note that the use of `RefreshView` instead of `Dirty` is _intentional_
here. The `RefreshView` flag is cleared before refreshing the view while
the `Dirty` flag is cleared at the very end. Using the `Dirty` flag
could have consequences because it is a more long-lasting change to the
view flags. Because `detectChangesInView` will immediately clear the
`RefreshView` flag, this change is much more limited and does not
result in a different set of flags during the view refresh.

The component fixture dependencies have to be passed in manually. This
is a bit annoying to manage as we expand which dependencies are needed.
Instead, we can run the constructor in the TestBed injection context and
move the dependencies into the component fixture code, as is done with
other constructors in Angular.

When there are ng-templates nested inside other ng-templates, the replacement and removal of the templates gets disrupted. Re-processing the templates in the file along the way resolves this issue.

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.

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.

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 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.

This commit fixes an issue with hydration, which happens when a content is projected in a certain way, leaving host elements non-projected, but the child content projected.
The fix is to detect such situations and add extra annotations to help runtime logic locate those elements at the right locations.

This commit updates the logic to handle hydration of multiple nodes projected in a single slot. Currently, in case component nodes are content-projected and their order is changed during the projection, hydration can not find the correct element. With this fix, extra annotation info would be included for such nodes and hydration logic at runtime will use it to locate the right element.

Currently the way we extract the pathname of a URL is by creating an anchor node, assigning the URL to its `href` and reading the `pathname`. This is inefficient and it triggers an internal security check that doesn't allow the `href` attribute to be set which ends up blocking https://github.com/angular/components/pull/28155.

Related to #52928 but `updateAncestorTraversalFlagsOnAttach` is called
on view insertion and _should_ have made that work for views dirty from
signals but it wasn't updated to read the `dirty` flag when we changed
it from sharing the `RefreshView` flag.
For #52928, we've traditionally worked under the assumption that this is working
as expected. The created view is `CheckAlways`. There is a question of whether we
should automatically mark things for check when the attached view has
the `Dirty` flag and/or has the `FirstLViewPass` flag set (or other
flags that indicate it definitely needs to be prefreshed).
