LGTM — simple CODEOWNERS addition.

Extended reasoning...

Overview

The PR adds a single path-specific entry to .github/CODEOWNERS, assigning @hbarclay as owner of experimental/operatorx/, following up on the operatorx import in #2234. This mirrors the existing style of path-specific entries already in the file (e.g. the AMD/NVIDIA master config lines).

Security risks

None. CODEOWNERS changes only affect review/approval routing on GitHub and do not affect runtime behavior, secrets, or code execution.

Level of scrutiny

Minimal scrutiny is warranted — this is a one-line, purely declarative config change with no logic, no tests needed, and no ambiguity in intent.

Other factors

The change is consistent with the existing file format and is a natural follow-up to the just-merged operatorx import. No outstanding review comments exist on this PR.
