perf(sync): the fork's signed commit with inbound merges and fast deletes

Browse source 
The offline sync package's shared part now comes from the fork's branch
halkyon/fast-deletes (b545035, signed), which stacks two changes on the
byte payload fix: onInboundMerge, called only when changes from the
remote peer were merged, which the app now reads again on rather than
after every save's sync; and local deletes that skip the foreign key
projection pass when it can't change it (8 s for one delete in a library
of 8,000 cards, 30 s for a card, now tens of milliseconds).

# The offline sync package's shared part from our fork: v0.0.10 with one fix,
# comparing byte payloads as bytes. v0.0.10 compares them byte by byte through a
# UUID parse that throws for each byte, so a sync touching a few thousand cards kept
# the server busy for minutes, answering nobody, while its client timed out and
# sent everything again (2026-10-12). Pinned to a signed commit of the fork's branch
# halkyon/byte-payloads; drop this once a release of the package has the fix.
