perf(sync): the fork's signed commit with fast merges, and #150 fixed

Browse source 
The offline sync package's shared part now comes from the fork's branch
halkyon/fast-merges (f062725, signed), adding two changes to the pin: a
merge only inserting new rows proven unable to change the projection
skips its passes (a rating another device made, received in a library of
8,000 cards: 9.5 s, now about 60 ms), and projections are rebuilt once
after the synced tables changed rather than on every session and merge
(upstream #150). AGENTS.md's note on #150 stays until a deploy runs it.
