What changed

• Add a live PyPI version badge.
• Make PyPI the primary installation path now that v0.1.0 is published.
• Link users to the latest GitHub Release and its verified distribution hashes.
• Replace README-relative images and links with canonical GitHub URLs so the content renders reliably outside the repository.

Why

The README still presented a source checkout as the default installation path after the first production release. Relative links also depend on GitHub repository context and are not portable when the README is used as package metadata.

Impact

New users get a one-command PyPI installation and clearer release provenance. The GitHub README improves immediately; PyPI metadata for 0.1.0 remains immutable, so the portable links will appear on the next package version.
