style(typescript): fix prettier formatting in tsExtractFunctionName

Single line-length fix in `gitnexus/src/core/ingestion/languages/typescript.ts`
flagged by `quality / format` CI on commit ef96603f. The unformatted block came
from the merge of upstream PR #1179 (`fix/issue-1166-calls-edges`) where the
`pair`-with-arrow / `pair`-with-string-key handling was added; prettier wanted
the `.find` callback inlined onto a single line.

No behavior change. Pre-commit hook would have caught this locally if the
husky postinstall step had been able to write `.git/config` on this dev machine.
