[bk201-]

This pull request introduces improvements for Cosmos DB integration and workspace management, including enhanced error handling, expanded localization, and support for new workspace views. It also updates dependencies and refines command activation conditions for better compatibility with the vscode-fabric.view.workspace. The changes are primarily focused on user experience, workspace integration, and dependency maintenance.

Workspace and Cosmos DB Integration:

• Added support for the vscode-fabric.view.workspace view in package.json, enabling Cosmos DB commands and features to be activated in this new workspace context. [1] [2] [3]
• Expanded command activation conditions to include vscode-fabric.view, ensuring Cosmos DB actions are available in both Azure and Fabric workspace views. [1] [2]

Localization and Error Handling Improvements:

• Added new localized strings for artifact, workspace, and database errors, as well as improved validation messages for names and credentials in l10n/bundle.l10n.json. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14]
• Removed unused or outdated localization strings related to graph resources, reflecting a shift away from graph-specific features. [1] [2] [3] [4]

Dependency Updates:

Codebase Cleanup:

Dependency Overrides:

• Added an override for @prantlf/jsonlint to use a specific version of ajv, ensuring compatibility and stability.
