Feat/vscode extension mssql

[ernstc]

This pull request migrates the SQL Data Inspector extension from Azure Data Studio to Visual Studio Code, focusing exclusively on Microsoft SQL Server (MSSQL) support through the official mssql extension. It removes support for MySQL and PostgreSQL, updates the extension's branding and documentation, introduces SQL command/result tracing, and modernizes the development and debugging setup.

Migration to Visual Studio Code and MSSQL:

• Migrated the extension to use the SQL Server (mssql) extension for connection management and query execution, dropping Azure Data Studio and support for MySQL/PostgreSQL. Only Microsoft SQL Server is now supported. (package.json, README.md, CHANGELOG.md) [1] [2] [3] [4] [5]

• Updated extension name, display name, version, and icon to reflect the focus on MSSQL and Visual Studio Code. (package.json, README.md) [1] [2]

New Features:

• Added SQL command and result tracing to the SQL Data Inspector output channel, with a new setting sqlDataInspector.tracing.sqlCommands to enable/disable this feature. (package.json, CHANGELOG.md, README.md) [1] [2] [3]

Development and Debugging Improvements:

• Replaced the build system with Vite, updated npm scripts, and removed ESLint and related configuration. (package.json, .eslintrc.json) [1] [2] [3]

• Updated VS Code launch and tasks configurations for improved debugging and build workflows, including new build/watch tasks and launch profiles. (.vscode/launch.json, .vscode/tasks.json) [1] [2]

Documentation Updates:

• Overhauled the README.md to document the new connection model, usage instructions for Visual Studio Code, and removed references to Azure Data Studio and non-MSSQL databases. (README.md) [1] [2]

Cleanup:

• Removed obsolete configuration files for ESLint and extension recommendations. (.eslintrc.json, .vscode/extensions.json) [1] [2]
