## Human Summary
MCP Registry 1.7.7 adds overlap matching for slice-valued OIDC claims and refactors request-body handling alongside dependency updates.

## Agent Summary
Review 1.7.7 for registry OIDC policies that use multi-valued claims; test overlap semantics and request handling before production rollout.

## Body
The notable behavior change is support for overlap comparison when OIDC extra claims are represented as slices. That makes authorization policies more compatible with identity providers that emit multi-valued claims. The release also removes duplicated request-body reading logic and updates deployment dependencies, so self-hosters should exercise both authentication and API regressions.
