Align claims with source behavior and verify packaging

[lukisch]

Summary

The repository now describes the manifest and installer as they work: install.sh fetches the listed Git sources and reports declared wiring labels. The bilingual entrypoints include the seven manifest refs/capabilities and a fetch/report diagram; the previous long guides remain archived with a supersession notice. Legal, security, and license statements are scoped to the direct project evidence.

The PEP 639 metadata keeps version 1.3.4 and produces a metadata-only wheel. An explicit source allowlist includes the documentation, tests, installer, workflows, and manifest. One Ubuntu CI job builds wheel and sdist, checks their metadata and contents, and installs the test extra from the unpacked sdist before running checks.

No runtime behavior, LICENSE, or NOTICE changed. No release or package publication is part of this PR.

Validation

• 32 tests passed on Python 3.13.15 from the working tree and from the unpacked sdist.
• Ruff, compileall, manifest JSON validation, bash -n, and git diff --check passed.
• PEP 517 wheel and sdist built with setuptools 84.0.0. The wheel contains eight .dist-info members and no Python modules; the sdist contains 35 files and its test extra installed successfully.
• The final patch retains the existing version 1.3.4.
