fastmcp 4.2.0a5 on Python PyPI

FastMCP 4.2.0a5 adds SkillManifestProvider, which serves skills from their manifests (frontmatter plus each file's digest and size) and reads a file only when a client reads it, so skills kept in a bucket or database don't have to be loaded to answer skills/list. SkillCatalogProvider now builds on it and no longer re-hashes every file on each request.

Since a4, a dependency can own the tool argument it reads through CallArgument, completion no longer suggests values for prompts or templates a caller can't see, ctx.info() and the other logging helpers work inside background tasks, and a final polish pass covered docs, examples and docstrings. This is the last prerelease before 4.2.0.

Thanks to our 128 contributors, including 54 first-time contributors.
