release(v4.2.1): fix concurrent-ratchet desync via OutboundQueue waiter cursor

Pull-mode httpClient + drainer + parallel RPCs against the same peer
deteriorated after ~10s with `DecryptionError`. Two bugs combined:

- `OutboundQueue.enqueue` woke `drain` waiters with a `since=0`
  snapshot, replaying already-processed events into
  `Shade.acceptTransferEnvelope` → `manager.decrypt` twice. The
  duplicate consumed an already-used skipped key and corrupted the
  Double Ratchet receive chain.

- `ratchetDecrypt` then propagated the corruption: a same-DH
  message behind the chain with no cached skipped key fell through
  to `kdfChainKey` on the ahead state and rewound `chain.counter`,
  permanently desyncing the chain.

Fix `OutboundQueue` to honor each waiter's `since`, and harden
`ratchetDecrypt` so any future duplicate fails cleanly without
mutating state. Adds regression coverage at all three layers.

+## [4.2.1] — 2026-05-04 — Concurrent-ratchet desync under pull-mode drainer
+
+A consumer running `shade.files.httpClient(server, { outboundQueueUrl, ... })`
+alongside parallel RPC traffic against the same peer would, after ~10s of
+load, see every subsequent message fail with
+`DecryptionError: Failed to decrypt message — wrong key or tampered data`.
+Two bugs combined to cause this; both are fixed in `4.2.1` with regression
+coverage.
+
+### Fixed
+
+#### `@shade/transfer` — `OutboundQueue` waiter cursor
+`enqueue` woke pending `drain` waiters with a `since=0` snapshot — the
+full event log — instead of using the waiter's own `since`. A poll that
+parked at the head and was woken by a fresh enqueue therefore replayed
+every event the waiter had already processed. Downstream the queue
+fed `Shade.acceptTransferEnvelope`, so the duplicate replayed an
+envelope into `manager.decrypt` twice. The second decrypt consumed an
+already-used skipped key and corrupted the Double Ratchet receive
+chain. Each `PendingWaiter` now records its `since` cursor and is
+delivered only events with `id > since`.
+
+#### `@shade/core` — `ratchetDecrypt` defense-in-depth
+A same-DH message whose `counter` was already behind the chain — and
+that did NOT match a cached skipped key — fell through to a path that
+called `kdfChainKey` on the *current* (ahead) chain key and then set
+`chain.counter = message.counter + 1`, permanently desyncing the
+ratchet so every subsequent decrypt returned wrong-key. Such messages
+are now rejected with `DecryptionError` without any state mutation, so
+a downstream replay (transport bug, retry, intermitent network) cannot
+poison the session.
+
+### Tests
+- `packages/shade-files/tests/integration/concurrent-ratchet.test.ts` —
+  100 parallel `httpClient` RPCs while the drainer runs, plus a mixed
+  workload of 50 RPCs + 50 raw `shade.send` deliveries with Bob
+  echoing replies through the queue. Both surface the bug pre-fix.
+- `packages/shade-transfer/tests/outbound-queue.test.ts` — direct
+  regression on the waiter `since` cursor.
+- `packages/shade-core/tests/ratchet.test.ts` — replay of an
+  already-decrypted message must throw cleanly without breaking
+  subsequent decrypts on the same chain.
