Subject: [PATCH] chore(ts): add root project references for editor tooling

Split shared compiler options into tsconfig.base.json so the root
tsconfig.json can describe the workspace project graph.

This lets TypeScript language servers resolve references across
package boundaries while keeping package builds on the same compiler
settings.
