chore: add package manifest, config source-of-truth and tsconfig

- package.json with pi section (extensions/skills/prompts) and Pi libs as peerDependencies (*)
- config/company.json as the single source of truth (values are TODO, gitHost set)
- tsconfig.json for optional local typecheck

package.json
