Note

Low Risk
Administrative-only change that affects review/approval routing, not runtime code or behavior.

Overview
Adds .github/CODEOWNERS to enforce review ownership: defaults all files to @torusresearch/Admins, assigns src/ and test/ to @torusresearch/Web3Auth-Product, and restricts changes to the CODEOWNERS file itself to @torusresearch/Admins.
