Subject: [PATCH 1/2] fix(maintainer): add .ts extensions so node can load the
 sweep

Node's type stripper does not resolve extensionless relative imports, so the scheduled sweep exits before it assigns anyone.

Subject: [PATCH 2/2] fix(ai-angular): extend tsconfig.base.json like every
 other package
