Switch to inclusive naming

Would it be possible to deprecate the term `overlap-whitelist`? I think a good replacement could be `overlap-allowlist`.

No files or tests are named. Start by searching the repository for `overlap-whitelist` and identify where the term is exposed or documented; confirm the project's deprecation conventions before assessing the required changes. Done means the inclusive replacement is supported and the old term is deprecated consistently, with relevant tests passing.
