Remove unused `@ts-expect-error`

Editor assessment

The subject states the cleanup exactly: an unused @ts-expect-error directive was removed. Type fix is defensible for a type-checking correction, scope api is accurate, and the exact directive name makes the change verifiable at a glance. No body, acceptable for a one-line removal whose justification (unused) is in the headline. No footers beyond the PR number. Hygiene is clean. A small, complete, noise-free message.
