Pull request overview

Adds a new read-only MCP tool list_repository_collaborators that wraps the GitHub REST endpoint for listing repository collaborators, returning a minimal output (login, ID, role name) and supporting an optional affiliation filter plus standard pagination. Implementation follows the existing tool patterns in pkg/github/repositories.go.

Changes:

  • New tool ListRepositoryCollaborators registered in AllTools under the Repos toolset.
  • New MinimalCollaborator output type and corresponding toolsnap, table-driven tests, and README entry.
  • Required repo scope; supports affiliation (outside/direct/all) and pagination params.
