Collect findings from other people's writing, with sources

The skill so far only held what we broke ourselves. Most of what is worth
knowing about a new SDK is found rather than suffered — release notes,
other people's articles — and that deserves a place too, on terms that
stay fair to whoever wrote it.

So: entries in our own words, source named and linked, and the one thing
no external article can supply — what it would replace in our code and
whether it is genuinely a step forward. Attribution answers plagiarism,
not copyright, so nothing is pasted; an API signature is a fact, the
paragraph explaining it is not ours to take.

First four entries come from Natalia Panferova's writing at nilcoalescing
.com: the close button role and concentric corners, both of which replace
things we hand-built; ScrollPosition, which replaces one wrapper view;
and the iOS 27 toolbar APIs, which we cannot use at our deployment target
but which would delete a workaround the day we can.

A LICENSE was overdue and now says plainly what is ours, what is Apple's
and stays out of the repository, and what belongs to the authors we cite.
