This commit **enables the TypeScript AI context provider by default** within the **Copilot completions core**. It changes the default value of the `chat.languageContext.typescript.enabled` configuration setting to `true`, ensuring that the AI context for TypeScript files automatically considers neighboring files for improved relevance. This **feature enablement** provides **enhanced AI completions** for TypeScript users out-of-the-box, improving the accuracy of suggestions without requiring manual configuration. Internal `featuresService` interfaces and implementations were updated to manage these new default settings for file inclusion and exclusion.

This commit **reverts a recent dependency upgrade** for the `minimatch` library within the **`npm` extension**, specifically undoing the bump from version `5.1.6` to `10.2.1`. This **maintenance rollback** restores the previous stable version of `minimatch` to avoid potential incompatibilities. As part of the revert, the import statement in `extensions/npm/src/tasks.ts` is also changed back from a named import `{ minimatch }` to a default import `minimatch`, aligning with the older library's API. The primary scope is to ensure the continued stability and functionality of the `npm` extension's task processing by reverting to a known working dependency version.

This change reverts the DMG builder to an older version, impacting the build process for macOS disk images. It likely resolves a build issue or restores stability in DMG creation.

This commit **updates the project's dependency lock file**, `package.lock`, to reflect the latest resolved versions of its direct and transitive dependencies. This ensures that the entire **build and runtime environment** consistently uses the specified package versions across all development, testing, and deployment stages. It represents a standard **dependency management** update, crucial for maintaining project stability and security by incorporating recent package changes.

This commit **reverts** the `dmg-builder` component to its previous stable version, `26.5.0`. This **maintenance rollback** addresses potential issues or regressions that may have been introduced by a more recent update to the builder. Consequently, the **macOS disk image creation process** will now utilize this specified version, ensuring consistent and reliable build outputs for macOS applications.

This commit performs essential **maintenance** by updating the project's external **dependency list**. It ensures the application relies on current and compatible versions of its required libraries, primarily impacting the **build system** and **project configuration**. This update helps to improve overall **stability**, potentially addresses known security vulnerabilities, and provides access to the latest features offered by these packages. By keeping dependencies current, the project maintains better compatibility within its ecosystem and streamlines future development efforts.

Update chatParticipantPrivate version to match vscode (#3714)

Merge pull request #294490 from microsoft/dbaeumer/anonymous-chickadee-chocolate

This commit introduces a **minor maintenance fix** to the **Chat feature's test suite**, specifically addressing an incorrect test skipping syntax. It **corrects the placement of the `.skip()` method** in `src/vs/workbench/contrib/chat/test/browser/widget/input/chatEditsTree.test.ts`, moving it to directly follow `test` in the test definition. This ensures that tests intended to be skipped within the **Chat widget's input edits tree tests** are properly ignored during execution. The change prevents potential false failures or unnecessary test runs, improving the reliability of the **testing infrastructure**.

This commit performs **maintenance** by **disabling three currently failing tests** within the `src/vs/workbench/contrib/chat/test/browser/widget/input/chatEditsTree.test.ts` file. These specific tests, which are part of the **Chat widget's input editing functionality**, were causing build failures in the CI pipeline. By applying `.skip()` to their definitions, the commit ensures the overall test suite remains stable and green, preventing false negatives. This temporary measure allows other tests to execute successfully while the underlying issues with these particular tests are investigated and resolved.

This commit introduces a **refactoring** within the **Copilot extension's TypeScript context service**, specifically enhancing the `NeighborFileModel` in `languageContextService.ts`. It modifies the `NeighborFileModel` to utilize a **static constant** for defining the maximum number of items it can hold, improving code clarity and maintainability. Additionally, a new check is implemented to ensure proper document consideration when files are closed, contributing to more robust management of neighboring file URIs. This change primarily affects the internal workings of how Copilot tracks relevant files for context, making the system more predictable.

This commit addresses a **bug** in the **Copilot extension's TypeScript context service** where irrelevant "similar files" context was being included in completion suggestions. It **refactors** the `NeighborFileModel` within `languageContextService.ts` to differentiate between visible and non-visible open files. This change ensures that **visible files are prioritized** for completion context and increases the overall number of relevant files considered. The fix prevents the insertion of "bogus" context, thereby improving the accuracy and quality of **Copilot's code completions**.

Merge pull request #291371 from microsoft/dbaeumer/moderate-finch-aquamarine

This commit introduces a **new capability** to collect **statistics** for context items provided by the **default diagnostic provider** within the **Copilot extension's completions prompt factory**. It **refactors** the handling of diagnostic bags by extracting it into a dedicated method, `addDefaultDiagnosticBag`, in `completionsPromptFactory.tsx`, which now includes the statistics collection logic. This enhancement improves the **observability** of diagnostic context item usage, aiding in future analysis and optimization of prompt generation for the **Copilot completions** feature. Additionally, a minor **refactoring** renames `setupExpectationsForDiagnostics` to `setupExpectationsForDiagnosticBags` for improved clarity within the diagnostic context providers.

This commit delivers a crucial **bug fix** for the **inline completions** feature, specifically within the **rename symbol tracker service**. It addresses an issue where the tracker failed to correctly handle **deletions** during symbol renames, potentially leading to incorrect tracking of user edits. The fix, implemented in `src/vs/workbench/contrib/inlineCompletions/browser/renameSymbolTrackerService.ts`, ensures that user edits involving deletions are now correctly recognized and processed by the logic. This significantly improves the overall reliability and accuracy of symbol renaming operations within the editor.

This commit **enhances the testing infrastructure** for the **`completions-core`** module by integrating `TestLanguageDiagnosticsService`. It specifically modifies the `extensions/copilot/src/extension/completions-core/vscode-node/lib/src/test/context.ts` file to add a definition for `ILanguageDiagnosticsService` using this test service within the test service collection. This **maintenance** update improves the **testability** of components that depend on language diagnostics, allowing for more controlled and isolated testing environments within the `completions-core` extension. The change ensures that tests can reliably mock or control diagnostic behaviors without external dependencies.

This commit introduces **NES rename functionality** to the `typescriptContext` extension, enabling advanced, context-aware renaming operations, particularly for "post-rename" scenarios. It establishes **new protocol definitions** for both prepare and execute phases, implements the **core rename logic** in `api.ts`, and integrates **server-side request handling** and **VS Code commands** to expose this capability. To support this **new capability**, the **testing infrastructure** is significantly enhanced with utilities like `runWithTemporaryFileUpdate` and new test cases, ensuring the robustness and backward compatibility of the feature. This work provides a more sophisticated rename experience within the Copilot extension's TypeScript context.
