Pull request overview

This PR refactors the .NET CLI's command-line parsing infrastructure to improve consistency and reduce dependencies. It introduces a new DotNetCommandDefinition class that serves as the root command definition, migrates all subcommand parsers from a GetCommand() pattern to a ConfigureCommand() pattern, creates new command definitions for nuget and completions commands, and removes the dotnet-watch tool's dependency on the main dotnet project. This significantly reduces the size of dotnet-watch from 390 files (43MB) to 206 files (26MB).

Changes:

• Introduced DotNetCommandDefinition as a centralized root command definition containing all subcommands
• Refactored all command parsers from a static GetCommand() pattern to instance-based ConfigureCommand() methods
• Created new command definition classes for nuget and completions commands with proper structure
