🛠️ Doc Gen v1.0.2 — Cleaner Project Discovery

Doc Gen v1.0.2 is a maintenance release that keeps dedicated virtual
environments out of generated project structures and improves repository
presentation.

- Ignore supported development, production, publishing, and auxiliary virtual
  environment directories during project discovery.
- Align Git, Docker, formatter, and linter exclusions with that behavior.
- Add regression coverage for environment-directory filtering.
- Refresh README metadata and add a portable CLI preview.
- Standardize public project contact metadata.

Existing commands, configuration, and dry-run behavior are unchanged.

- Version: `v1.0.2`
- Previous version: `v1.0.1`
- Release type: patch
- Package compatibility: Python 3.9+
- Stability: stable
