Currently when we reuse a Tsurge migration is reused externally, there's some glue code that needs to be executed in a specific order. The code gets copied between the different migrations which is error-prone and means that bugs may have to be fixed several times.
These changes move the common steps out into a separate function so that only the migration-specific logic (mostly instantiation and logging) is left in the schematic.
PR Close#60386
Usage of the `fast-glob` package has been replaced with the `tinyglobby` package. The change reduces the number of transitive dependencies related to these packages from 17 to 2 while also maintaining equivalent functionality. This was also changed in the Angular CLI packages.

This commit fixes an issue when ts files are referenced multiple times (and thus analyzed multiple times) for example from a `tsconfig.json` and `tsconfig.spec.json`.
PR Close#60065
If a file ends up in multiple programs, the unused imports migration was counting it twice. This was fine since the string replacements were handling it correctly, but it was printing out incorrect data.
These changes rework the migration to de-duplicate the replacements and produce the data from the de-duplicated results.
PR Close#59656
We previously did count forcibly ignored queries as incompatible. This
resulted in incorrect migration stats that are printed upon migration
completion.

This ensures the migration works for these TypeScript versions. The
migration is very sensitive to the TS version and its internals; so it
makes sense to test all of these.
PR Close#59463
In v19 we added a warning about unused standalone imports, however we didn't do anything about existing code which means that users have to clean it up manually. These changes add the `ng g @angular/core:cleanup-unused-imports` schematic which will remove the unused dependencies automatically.
There isn't any new detection code since all the manipulations are based on the produced diagnostics, but there's a bit of code to remove the import declarations from the file as well.
Fixes#58849.
PR Close#59353
Fixes that in some cases the internal version of the migration was dropping code when all the statements after the `super` call are deleted.
PR Close#58959
Skips the TS version check in tsurge since it's blocking some internal changes and generally isn't necessary since the app will be checked when it's built anyways.

Priori to this commit, initializer functions with dependencies were not migrated correctly.
With this commit, the function is executed in a injection context to allow the usage of `inject`.
PR Close#58518
Before, in a situation like shown in the test, all of the initializers
would be dropped, as the code would try to insert it at the hoisted
property which is going to be deleted.
PR Close#58804
This fixes an issue where the lazy-routes migration would crash for component classes a
decorator without arguments in front of the `@Component` decorator (in particular, it needed
to be the first decorator).
Fixes#58793
PR Close#58796
Adds some logic to the `inject()` migration that allows is to handle parameter declarations with initializers. This was omitted initially, because we don't officially support such cases, but it came up internally.

```html
<button (click)="someSubject.next()">Click</button>
```
was migrated to an `.emit` call, even if `someSubject` was not an `EventEmitter`.
The issue was the same in host listeners.

A dot was appearing in the middle of the comment for `DerivedIsIncompatible`.
While at it, a dot was missing in `ClassManuallyInstantiated`.

In #57684 the standalone migration was changed so that it replaces any leftover modules with their `exports`, in an attempt to preserve more working code. These changes expand that logic to also cover tests since it's somewhat common internally to only import a component's module without having any references to the component.
Note that tests are a bit of a special case, because we don't have access to the template type checker, so instead we copy over all of the `exports` of that module.

Running `ng g @angular/core:signals` prompts for the question on which migration to run and offers 3 options (inputs, outputs, queries).
Running with `--defaults` skips the prompts, but only runs 2 of them.
This fixes it by including the `outputs` migration in the default ones.

This commit improves the temporary variable generation in signal
migrations, whenever references are "shared" inside property
declarations.
PR Close#58581
Currently whenever we would come across a code snippet like this, where
`maxCellsPerRow` is an input, the control flow analysis would fall apart
because the first occurence of the node points to a control flow node
that is offset-wise "after" the first occurence. This commit makes the
logic more robust.
PR Close#58581
Previously we always ran Tsurge migrations with an Angular program, even
if it's a plain `ts_library` target. This has changed now, so we also
need to properly handle the case where a `ts_library` is analyzed, but
no Angular program is available.
PR Close#58541
Tsurge can run against the full Google3 depot, and will often also deal
with plain `ts_library` targets. Those shouldn't be constructed with the
Angular compiler as this could cause out of memory breakages etc. The
targets are simply not "proven" to be compatible with the Angular
compiler; so we shouldn't use them when not necessary.
PR Close#58541
We were not properly passing around the TCB full program optimization,
so TCB generation was done per individual file. This significantly
slowed down reference resolution.
PR Close#58525
The use of relative imports vs. module imports and the existing mismatch
can cause symbols to be duplicated in migrations. This is problematic as
it breaks migration logic or compiler logic in the worst case.
Long-term we will solve this by having a better Bazel toolchain where
both relative and module imports can point to the same files; but in
practice this is not the case right now.
This commit fixes the fallback template logic in the signal
input/queries migration; in case no type check block information is
available.
PR Close#58515
Before v19, the default value of the standalone flag was false, this code change flips the logic in the migration to make it true by default.
PR Close#58474
Updates the internal part of the `inject` migration to attempt to correct some cases where the declaration order of properties doesn't match the initialization order.

We were repeating the logic that deletes a node together with all its comments in a few different places. These changes consolidate the logic under `ChangeTracker.removeNode`.
