The GIF picker was a bare Giphy search grid with no memory of what you've
sent, so re-sending a go-to reaction GIF meant re-typing the search every
time. Add a "Recent" row at the top of the picker (default view; hidden
while searching) for one-click re-sending.
- New persisted state state/recentGifs.ts: recentGifsAtom (localStorage,
cinny_recent_gifs_v1, getOnInit) + pure addRecentGif (dedupe-by-url
move-to-front, cap 16, ignore empty url), with 5 unit tests.
- GifPicker records every sent GIF (from search or the Recent row) to the
front, and renders a 3-up thumbnail grid of recents above the search
grid when there are recents and no active search term. Section label
matches the picker's existing `// GIF_SEARCH` treatment (lotusTerminal)
or a muted label otherwise.
