Add linters to enforce clean code standards in the MCP repository

[anannya03]

Introduce linting checks into the MCP repository to improve code quality, enforce consistency, and reduce manual review overhead.

• Rosalyn Analyzer
• Parameter Generation Linter (Code as Source of Truth) - Add a linter that generates optional and required parameters directly from code definitions, allowing code to act as the authoritative source of truth. (similar to the metadata generation)
• All class files should contain a namespace and copyright statements.

Will add more linters in this list as we think of it.
