* feat(ios): durable offline command outbox for chat sends
Text messages sent while the gateway is unreachable queue in a durable
per-gateway outbox (new outbox_commands table in the per-gateway chat
cache SQLite store, schema v2) instead of failing. Queued bubbles render
with visible Queued/Sending/Not sent states and flush strictly in
createdAt order once transport health recovers; each command's client
UUID rides as the send idempotency key, so at-least-once delivery plus
gateway dedupe keeps the transcript exact.
Contract summary:
- Bounds: 50 queued commands per gateway; refused enqueues keep the
draft. Queued rows older than 48h expire to failed("expired") rather
than silently sending stale commands; tap-to-retry refreshes
createdAt so an expired row can resend as new intent.
- Failure taxonomy: transport-level failures keep rows queued without
burning retry attempts (backoff ladder, then health drops so the
reconnect machinery owns pacing); gateway rejections burn attempts
and fail terminally after 3, with context-menu retry/delete.
- Deletes are tombstoned synchronously and rechecked after the claim
await so an active flush can never send a removed command; Delete is
hidden while a bubble is already in flight; offline enqueue is
guarded against double submit during the health probe.
- Post-reconnect live sends route behind draining outbox rows (FIFO),
and a cold open assumes a backlog until restore adopts durable rows.
- Crash safety: 'sending' rows revert to 'queued' at startup; flushed
turns are spliced into the session's cached transcript before their
outbox row is deleted, and stale history snapshots cannot evict a
just-flushed turn until a snapshot confirms it.
- Per-gateway scoping and purge ride the transcript cache: one SQLite
file per gateway; reset/forget drops the queue with the cache.
Fixture/unpaired transports get no outbox.

* chore(ios): sync native i18n inventory
* style(chat-ui): satisfy strict SwiftFormat lint (doc comment, scope blank line)
* feat(ios): read-only offline cache for chat sessions and transcripts
Cache-first cold open for the iOS chat tab: the last known transcript and
session list render immediately from a local SQLite cache, then live gateway
history replaces them wholesale through the existing reconciliation path.
When the gateway is unreachable, recent sessions and transcripts stay
browsable read-only; sending remains gated by the existing connection state.
- New OpenClawChatTranscriptCache protocol seam plus SQLite-backed store in
OpenClawChatUI (raw SQLite3, no new dependencies), scoped per gateway
stableID so transcripts never leak across paired gateways.
- Bounds: 50 sessions, 50 transcripts, 200 messages per session; text rows
only (attachment/binary payloads and tool arguments are stripped).
- Disposable cache: schema versioned via user_version; any open/schema/decode
mismatch drops and rebuilds silently. File protection
completeUntilFirstUserAuthentication on iOS.
- View model pre-paints from cache only until a live response applies
(hasAppliedLiveHistory/hasAppliedLiveSessions guards); write-through is
chained and off the render path.
- iOS wiring keys the chat view model identity on transport mode plus cache
gateway ID so switching paired gateways rebuilds the view model.
