feat(ios): v0.13 read-only catch-up — goal pill, queue chip, Kanban diagnostics, Curator archived, Platforms (WS-9)

Mirrors the v0.13 surfaces from WS-2 (Persistent Goals + ACP /queue),
WS-3 (Kanban diagnostics + hallucination gate), WS-4 (Curator archive),
and WS-5 (Google Chat platform + cross-platform allowlists + behavior
toggles) onto ScarfGo. Per Phase H precedent, every iOS surface is
strictly read-only — write verbs (Verify / Reject, /goal --clear, queue
send, allowlist editing, archive Restore / Prune) live on Mac in v2.8.0
and are deferred to v2.8.x.

Five iOS additions, all capability-gated so pre-v0.13 hosts see the
v2.7.5 layout unchanged:

1. Chat — goal pill ("Goal: <text>") and queue chip ("N queued") render
   inside `projectContextBar` whenever a project, goal, or queue is
   present. The bar is no longer project-only; goal/queue chips render
   even outside a project chat. Goal text scales with Dynamic Type
   (semantic `.subheadline`); the full untruncated text rides VoiceOver
   via the chip's accessibility label.
2. Kanban — `ScarfGoKanbanDetailSheet` gains a `retries: N` chip in the
   header `FlowLayout`, a yellow "Worker-created — verify on Mac" badge
   for `pending` hallucination state, a red "Auto-blocked" banner with
   the server-supplied `auto_blocked_reason`, and tappable diagnostics
   chip-lists (task-level + per-run) that present a new
   `DiagnosticDetailSheet` with kind / severity / message / timestamp.
   No Verify or Reject buttons; the badge copy points users to the Mac
   app.
3. Curator — `CuratorView` appends a read-only "Archived" section that
   loads via `viewModel.loadArchive()` on appear and pull-to-refresh.
   Per-row name + category badge + reason + archived-at + size; footer
   signposts users to the Mac app for Restore / Prune.
4. Settings → Platforms — adds a Google Chat status row (configured /
   not configured), busy-ack and restart-notification rows summarized
   across `gatewayPlatforms` (yes / no / mixed (N platforms)), and
   collapsed DisclosureGroups for allowed channels / chats / rooms with
   monospaced "platform: id" entries when expanded. No editor.
5. Settings — green "v0.13 features active" `ScarfBadge` above the
   quick-edits section when `caps.isV013OrLater`. Tap presents a new
   `V013FeaturesSheet` listing the six v0.13 surfaces with one-sentence
   summaries; the section footer is explicit that editing lives on Mac.

Implements WS-9 of Scarf v2.8.0 (Hermes v0.13.0 catch-up).
Plan: scarf/docs/v2.8/WS-9-ios-v0.13-plan.md (on coordination/v2.8.0-plans).

 Scarf v2.7.5 promotes Kanban from a read-only list to a full board with drag-and-drop, every Hermes write verb wired up, and per-project boards bound to a Scarf-minted tenant slug. The list view is preserved as a `Board | List` toggle for accessibility / narrow-window fallback.

+/// Direct YAML editor for `gateway.platforms.<platform>.allowed_<kind>:` list
+/// blocks. Hermes v0.13 added these list-valued keys, but `hermes config set`
+/// stringifies arrays (the same gotcha that forced Home Assistant's watch
+/// lists to stay read-only). The Messaging Gateway editor sidesteps the CLI
+/// for these keys by editing `~/.hermes/config.yaml` directly.
+///
+/// **Pure-function `setList`** is the heart of the editor — it splits the
+/// YAML into lines, finds (or creates) the targeted block, and splices the
+/// new items in while preserving every byte outside the block. The async
+/// `saveList` wrapper wires it through `ServerContext.readText` /
+/// `writeText`, so the same code path works on `.local` and `.ssh` servers
+/// — local goes through `LocalTransport`, remote round-trips via SCP.
+///
+/// **Scalar fields don't go through here.** `busy_ack_enabled`,
+/// `gateway_restart_notification`, and `slash_command_notice_ttl_seconds`
+/// are scalars that `hermes config set` handles cleanly — `GatewayBehaviorViewModel`
+/// routes those through `PlatformSetupHelpers.saveForm` like every other
+/// platform toggle.
+///
+/// **Why not use a real YAML library?** Same answer as everywhere else in
+/// Scarf: zero external dependencies. The Hermes config flavor is a tightly
+/// scoped subset (indent-based blocks, scalar-or-list values, no anchors /
+/// aliases / flow style), and the targeted edit doesn't need to understand
