Introducing Scalar: Git at scale for everyone

Introduces Scalar, a .NET Core application designed to accelerate Git workflows for large repositories. Scalar maximizes Git command performance by setting recommended config values, running background maintenance (commit-graph updates, packfile cleanup, loose object cleanup), and supporting the GVFS protocol for cloning. It also details lessons learned: focusing on relevant files, reducing object transfer, and not waiting for expensive operations. The post outlines quick start guides for existing repositories and GVFS protocol usage, and discusses plans for contributing Scalar's features to the core Git client.
