Pull request overview

This PR refactors the logging framework to support global configuration and improves documentation across the project. The changes introduce a flexible logging system that allows both global static logger configuration and per-instance logger injection.

Changes:

• Introduced a new global logging configuration system via LogOptions class with thread-safe static logger factory and fallback logger
• Added comprehensive test coverage for the new logging framework with 150+ lines of xUnit tests
• Upgraded from xUnit v2 to xUnit v3 and improved test naming to follow MethodName_Scenario_ExpectedBehavior convention
• Enhanced documentation with new CODESTYLE.md and AGENTS.md files, and expanded copilot instructions
• Improved code organization by reordering members to follow StyleCop-like conventions and converting #pragma suppressions to attributes
• Removed redundant Husky build targets from all projects and SourceLink from non-packaged projects (Console, CodeGen)
• Fixed resilience handler logic to properly handle both exceptions and non-success status codes
