Connect timeouts and rate limit issues

• Extension version: Any
• VSCode Version: 1.112.0
• OS: macOS 15.7.3
• Repository Clone Configuration (single repository/fork of an upstream repository):
• GitHub Product (GitHub.com/GitHub Enterprise version x.x.x): Github.com

When running the extension I frequently find it freezing or unresponsive when starting up. When checking the output logs of the extension I can see it's running either in connect timeouts or getting rate limited by Github. This seems like there's too much concurrent calls being made by the extension.

It's really frustrating to me. On the one hand the extension is really useful when it works properly, code navigation when reviewing from within your IDE is sublime. But the number of times the extension freezes or stops working after a new release makes it impossible to work with for me.

Steps to Reproduce:

1. Open VSCode
2. Try to load the extension

Beginne beim Start der Extension und verfolge die in den Logs beschriebenen PullRequest-Anfragen der GitHubRepository GraphQL API. Reproduziere das Einfrieren mit den aufgeführten VS Code-Schritten und beobachte dabei gleichzeitige Aufrufe, Rate-Limit-Fehler und Verbindungs-Timeouts. Als abgeschlossen gilt die Aufgabe, wenn der Start GitHub in diesem Szenario nicht mehr überlastet und die Extension nicht mehr unresponsive bleibt.
