Kam 628f3f99db docs: add Turkish community translation of Angular documentation 
add a link to the community-driven Turkish translation of Angular
documentation to make it easier for Turkish-speaking developers to
discover localized docs.

the barrier to entry and supports wider Angular adoption in the
Turkish-speaking developer community.

Kristiyan Kostadinov c822bf8e76 fix(compiler-cli): always parenthesize object literals in TCB 
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.

Kristiyan Kostadinov f8b6bd0cbe refactor(compiler-cli): escape quotes used in string expressions

Leon Senft 670d1660c4 feat(forms): add 'blur' option to debounce rule 
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.

Doug Parker 05d022d5e6 fix(compiler-cli): ignore generated ngDevMode signal branch for code coverage 
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.

Fixes #64583

Andrew Scott 1df1697c6e fix(compiler): prevent mutation of children array in RecursiveVisitor 
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.

Always ensure that the nonces you provide are <strong>unique per request</strong> and that they are not predictable or guessable.
If an attacker can predict future nonces, they can circumvent the protections offered by CSP.
Generating a nonce at the origin server is generally discouraged when using a CDN, as responses are frequently cached. If the server generates a nonce and the CDN caches that HTML response, every subsequent visitor receives the same "unique" value, allowing an attacker to discover the static value and bypass CSP protections.
To maintain the "one-time-use" integrity of a nonce, it should ideally be generated at the Edge layer (e.g., CDN) just before the content is delivered to the user.
</docs-callout>
NOTE: If you want to [inline the critical CSS](/tools/cli/build#critical-css-inlining) of your application, you can not use the `CSP_NONCE` token, and should prefer the `autoCsp` option or set the `ngCspNonce` attribute on the root application element.
