v0.15.1

The project describes itself consistently on PyPI, npm and in its README, and its documentation base is the unified site.

Fixes

• The project describes itself consistently on PyPI, npm and in its README. The package summary, the npm wrapper summary and the README opening each said something different, and the PyPI page carried no project links, keywords or classifiers.
• Documentation links point at the unified site. The declared docs base was the retired per-project host; it is https://smmh.dev/claudestream/ now, so generated sitemaps, feeds and llms.txt name the address that serves the pages.
