feat: add get_reviewers and get_status_checks methods to pull_request_read

Extends the pull_request_read tool with two new methods:

- get_reviewers: returns pending reviewer requests (both individual users
  and teams) using the PullRequests.ListReviewers API. This fills a gap
  in the existing toolset — requested team reviewers were previously
  not exposed anywhere in the MCP server.

- get_status_checks: returns a unified view of all status checks for a
  PR's head commit by combining legacy commit statuses (e.g. Atlantis
  plan/policy results) and modern GitHub Actions check runs into a single
  response with a top-level combined_state.

New output types added to minimal_types.go:
  - MinimalReviewerUser, MinimalReviewerTeam, MinimalPRReviewers
  - MinimalCommitStatus, MinimalStatusChecks

Adds unit tests for both methods (success and API-failure paths),
regenerates the pull_request_read toolsnap, and updates the generated
README tool documentation.
