Fix CI typecheck: build contracts before typechecking dependents

- Change turbo typecheck task to dependsOn: ["^build"] so the contracts
  package generates .d.cts/.d.mts declaration files before downstream
  packages run tsc
- Revert contracts types back to generated declaration files
- Remove unused useGitState.ts that imported missing @tanstack/react-query
