GitHub MCP Server v0.19.0

📚 Documentation

Improved GHES/GHEC visibility in README - Restructured documentation to better highlight GitHub Enterprise Server and GitHub Enterprise Cloud configuration, including fixes to example URLs that were previously causing confusion (#1210) - @tonytrg

Flexible toolset configuration - Added option to ignore unknown toolsets instead of raising errors, providing more flexibility in configuration scenarios (#1202) - @omgitsads

Consolidated pull request review tools - Unified multiple PR review tools (create_and_submit_pull_request_review, create_pending_pull_request_review, submit_pending_pull_request_review, delete_pending_pull_request_review) into a single pull_request_review_write tool with a method parameter (create, submit_pending, delete_pending). Validated against curated datasets with no regressions across models (#1192) - @almaleksia
Simplified Registry release pipeline - Streamlined the registry publication workflow by using version tag triggers instead of repository dispatch, removing the need for elevated permissions. Added a 5-minute wait mechanism to ensure Docker image availability before MCP Registry publication (#1204) - @MattBabbage

Reduced workflow permissions - Registry release pipeline no longer requires elevated actions:write permissions, minimizing security risk (#1204) - @MattBabbage
