fix(packages): fix type errors in consolidated packages + add missing files

- credits: fix mobile import paths (./operations → ../operations)
- feedback: fix createFeedbackService import (./feedback → ./api),
  recover missing types.ts from git history
- help: add package files (were untracked after consolidation)
- Update lockfile after package restructuring

All packages pass tsc --noEmit (excluding expected .svelte imports).
