Duncan 323bf68107 fix(sidebar): make outbox records write-once so foreign reclaim is race-free
The per-window token/recheck reclamation still performed a non-atomic
compare-then-delete on a mutable foreign key: a live owner could rewrite
its key between the reclaim decision-read and the removeItem, and the
whole-blob `queuedAt <= head.created_at` gate dropped same-second and
legacy `queuedAt=0` records that had not provably lost LWW.

Records are now write-once: a key is `<prefix>:<pubkey>:<relay>:<nonce>:<seq>`
and is never rewritten. A new edit writes a new key (next zero-padded seq)
then deletes its own older keys (write-before-delete, so a crash leaves at
least one record). Foreign reclamation reads an immutable record, proves it
reclaimable against durable relay evidence, and deletes it with no recheck.
Whole-blob supersession is strict (`queuedAt < head.created_at`); replay runs
before reclamation in every hook so a same-second record is consumed into
pending first; the legacy v1 shared key is only ever replayed, never deleted.
