Cut comment and docstring volume roughly in half across src, tests,
examples, and docs_src: removed comments that restate the adjacent code,
leftover development narration, section banners, and self-evident
Args/Returns blocks, and compressed the remaining docstrings to a
Google-style summary line plus only the detail that earns its place.
Kept (and tightened) the load-bearing content: Raises sections,
deprecation and version-availability notes, spec/RFC/issue references,
why-comments for non-obvious decisions, and all coverage pragmas. The
generated mcp_types.v* wire modules are untouched.
