Auto-threading, history pagination, streaming toggle + tool/reasoning display settings

- Auto-threading (Telegram topic-mode workflow): message.send {auto_thread}
  mints a fresh AI-named thread (instant derived title, LLM upgrade via
  channel.renamed); channel.created {auto:true}; the app jumps into the new
  thread and relocates the optimistic pending bubble.
- history frame: paged full message history for initial channel open /
  scroll-up pagination (reconstructed from the outbox log).
- Streaming on/off: gateway side (display.platforms.android.streaming) plus a
  per-device app toggle (Settings → Streaming); reasoning/model/tokens carried
  on message frames.
- Context menu: long-press (touch) / right-click (desktop) thread affordances
  via a KMP rightClick expect/actual.
- Settings → Reasoning: auto-collapse long reasoning blocks (default on).
- Tool detail: the gateway now always supplies full tool data — it forces
  verbose tool progress (full args → tool.start.args) and captures each
  completed call via the post_tool_call hook (output/duration/ok → tool.end).
  The app reveals the full call + output on expand (Truncated) and
  auto-expands cards in Everything mode.
