Refactor error handling and calculations in TheilU, Wmape, and TukeyBiweight classes; update buffer handling for consistency

- Updated buffer handling in TheilU and Wmape classes to ensure consistency after adding new values.
- Changed the resync interval constant in TukeyBiweight for better clarity.
- Refactored state structures to record structs in Gauss, Hann, Hp, Hpf, Kalman, Loess, Notch, and other filter classes for improved performance and readability.
- Enhanced numerical stability in Mama class calculations using Fused Multiply-Add (FMA) for precision.
- Added comprehensive tests for Atan2 validation to compare .NET's Math.Atan2 with PineScript's implementation, ensuring accuracy across various edge cases.
- Updated NDepend badges to reflect changes in classes, methods, and lines of code.

 # Codacy Rules
 Configuration for AI behavior when interacting with Codacy's MCP Server
 
+## using any tool that accepts the arguments: `provider`, `organization`, or `repository`
+- ALWAYS use:
+ - provider: gh
+ - organization: mihakralj
+ - repository: QuanTAlib
+- Avoid calling `git remote -v` unless really necessary
+
 ## CRITICAL: After ANY successful `edit_file` or `reapply` operation
 - YOU MUST IMMEDIATELY run the `codacy_cli_analyze` tool from Codacy's MCP Server for each file that was edited, with:
  - `rootPath`: set to the workspace path
