Pull request overview

Adds “view check run logs” support to the PR experience by wiring check run identifiers through GraphQL/models, exposing a new checkrunlog: document, and adding a webview button to open logs for failed checks.

Changes:

• Add a “View Logs” icon button for failed check runs in the PR status checks webview and route the request to the extension host.
• Introduce a checkrunlog: text document content provider and a corresponding URI scheme to display fetched logs in an editor.
• Plumb databaseId/isCheckRun through GraphQL and status check models, and extend the LM tool to include logs for failed checks.
