Spec v0.81: the door an author could not find. An uploaded archive is a
fifth install source, so an extension written on a laptop reaches a
remote Station without being published to git first; every seam declares
its handler's contract and the conformance kit checks the signature at
install, reading the source and never importing it; and the L.16
authoring surface serves prose that is written beside schemas that are
derived.

extensions/whisper moves to ">=0.81,<0.82" with the bump rather than
after it. It shipped declaring ">=0.79,<1.0", which under the versioning
policy this release writes down is a range that promises what nobody
keeps: the extension this project ships should pin the way it tells
everyone else to. Its suite reads monkeyllm.__version__ instead of a
literal, so the range is actually exercised and a failure at the next
minor is the pin working.
