This is a follow-up to #67381 which introduced a subtle bug where depending on the type checking configuration, we may put an object literal directly in the TCB body which the TS compiler ends up interpreting as a block. These changes resolve the issue by always wrapping the literal in parentheses.
TypeScript has functionality that automatically escapes quotes in string literals. These changes update the places where we may need to do the same ourselves.
Expands the `debounce` rule configuration to accept `'blur'`. When this option
is provided, the rule will delay model synchronization until the field loses
focus (is touched). This introduces a debouncer that defers resolution
until the framework automatically aborts pending debounces upon touch events.

The Angular compiler unconditionally adds a debug name transform for signals
which generates a conditional on `ngDevMode` (e.g., `ngDevMode ? { debugName: "xyz" } : []`).
During testing, `ngDevMode` is true, so the true branch executes but the
false branch is never executed. Consequently, coverage tools report the
false branch as an untested line/branch, preventing 100% test coverage.
This commit adds a synthetic `/* istanbul ignore next */` comment to the
generated false branch so that Istanbul ignores it. We only include the
istanbul comment (instead of additionally including c8) to focus on the
established standard for Angular CLI/Karma coverage while maintaining
compatibility with modern Vitest setups, since @vitest/coverage-v8 now
natively respects the fallback istanbul comment.

RecursiveVisitor.visitIfBlockBranch was permanently mutating the children array by pushing the expressionAlias into it. This change clones the array before pushing to avoid this side effect.

When routing between two different routes, child animations were not finishing, causing elements to be left behind in the dom. The fix ensures the proper fallback is handled to avoid automatically cancelled custom events. This ensures the animation-fallback cancelling the animation actually completes, and ensures the element is removed.

Partially rolls back to using TypeScript 5.9 for the builds on the patch branch, because we bundle our TypeScript version with the language service which can introduce unexpected breakages for users.
Note that we still allow users to install TypeScript 6.
Previously, Blob values were passed to `Uint8Array` this resulted in silently producing an empty array (length = 0) without throwing an error, leading to empty cached data

Use feature detection for `Uint8Array.prototype.toBase64` and
`Uint8Array.fromBase64`, falling back to the existing implementation
when native support is not available

This updates the state manager to allow intercepting and deferring commits of traversal navigations.
The issues that were encountered in the past appear to be resolved in Chrome.
The behavior of redirect is still undefined in this case, so there is an added TODO.

This ensures that when calculating longest animations, we completely ignore infinite animations. This will prevent mistakes with using the API and hopefully catch any unexpected bugs.

This addresses a reported issue where elements were being fully removed from the DOM during drag and drop operations.

(cherry picked from commit 0b59cba85d)
Translators are not allowed to write HTML which creates URI attributes. I opted to ban any values going into an attribute at all, to prevent even links to malicious content, rather than just sanitizing URIs.
I also converted this blocklist into an allowlist. Now, we only allowing setting known attributes (while sanitizing URI attributes). This significantly reduces risk of missing a vulnerable attribute and does not require an exhaustive list of all potential attributes.
BREAKING CHANGE: Angular now only applies known attributes from HTML in translated ICU content. Unknown attributes are dropped and not rendered.

Aligns the errors returned from the `parse` function in
`transformedValue` to use the same convention as the rest of signal
forms (a property called `error` that can contain a single error or list
of errors)

Add help link to extended template diagnostic messages to provide
users with additional guidance and documentation resources. This
enhancement improves developer experience by making it easier to
understand and resolve complex template issues through direct
access to relevant Angular documentation with detailed examples
and explanations for each diagnostic type.

The JsonPipe does not unwrap signals and `JSON.stringify` will return `undefined` for signals.
To avoid confusion, we log a warning when a signal is passed to the pipe.

Wrap `@defer` trigger expressions (`when`, `prefetch when`, `hydrate when`)
in a conditional context within the TCB to enable TypeScript's TS2774
diagnostic for detecting functions used without invocation.
Previously, signals and functions passed to `when` triggers without
parentheses would silently evaluate to truthy, causing unexpected behavior.
Now the compiler reports an error when a function is used as a condition
without being called.

avoid per-file semantic diagnostics work when warming up a newly loaded project.
