A sibling's version is its latest git tag (v1.4.0, or v1.4.0+3 for commits
after it), or, without tags, its commit's date and short hash, like
CoreDesktop's own. The version shown as available is that of the newest
commit on the default branch, which is what update installs.
sibling list shows each sibling's version. sibling check fetches every
sibling at once and shows which have a newer version, and sibling update
[name...] updates the named siblings or all of them. 71-siblings.sh now
runs sibling update, so update and version share one way of updating.
version lists the installed siblings with any newer version and, when run
in a terminal, asks for each one whether to update it now. version --check
and the update notification still only look at CoreDesktop.
The sibling skill docs describe how to release a version by tagging it.

`sibling` asks for a git URL, clones the repo into
~/.local/share/siblings/<name>, runs its install.sh and confirms the
install. `sibling list` and `sibling remove` manage installed siblings.
updates.d/71-siblings.sh pulls every sibling during `update` and runs
its update.sh, reporting failures in the update summary.
Document the sibling contract in skills/sibling-project-format.md and
update the custom-hook guide to match.
