Add CLI tool for generating DSL sample configuration

[Pressacco]

Summary

• factor the DSL sample XML into a shared helper so it can be reused

Pull Request Overview

This PR refactors DSL default constants into a shared static class and introduces a command-line tool for generating DSL configuration files. The analyzer constants (DefaultDslFileName and DefaultDslXml) are extracted from DslTerminologyAnalyzer into a new DslDefaults class, which is then reused by both the analyzer and a newly created console application.

Key changes:

• Extracted DSL defaults to a shared DslDefaults class for reusability
• Added BlueDotBrigade.Analyzers.Tool console application with a generate-dsl command
• Updated documentation with usage examples for the command-line tool
