chore: reformat after editorconfig update

Updated .editorconfig to set indent_style=space and indent_size=4 for C# files. Reformat all .cs files to apply the new indentation settings. No code logic changes, just whitespace reformatting.
also updated some comments in files in shorter and Precise way. No logic changes, just comment rewording for clarity and conciseness.
