Monorepos

Note	Draft placeholder — outline notes only; prose not yet written.

Points this section needs to cover:

Monorepo trade-offs versus many-repo setups (with submodules as the many-repo glue — cross-reference Ch 5, Git Toolkit)
Putting the chapter together: partial clone + sparse checkout + Scalar
background maintenance as the standard monorepo client setup
Repository layout and ownership practices
Real-world deployments (e.g. Microsoft Office/Windows on Scalar)
Forge support constraints and server-side considerations
