Organizing zod-plugin directories (#2921)

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

- Chores
- Use src-based entry points for bundling/types and align metadata
resolution with project layout.
- Broaden lint ignore patterns to cover generated/dist and coverage
folders.

- Tests
- Point test setup and test imports to source entry points for
consistency.
  - Expand test discovery to include nested test files.

- Refactor
  - Standardized internal module resolution across the codebase.

No user-facing behavior changes.
