docs: deep audit — registry drift, stale claims, 2-week PR coverage, dashboard screenshot (#40952)

Full-corpus correctness audit of the hand-written docs against the codebase,
plus a 2-week merged-PR coverage sweep and one live dashboard screenshot.

Correctness (verified against COMMAND_REGISTRY / PROVIDER_REGISTRY / TOOLSETS /
tools.registry / DEFAULT_CONFIG / source):
- reference: add /version slash command, context_engine toolset, openai-api +
  novita-ai to --provider; fix tool count 64->71; model_catalog ttl 24->1;
  add profile describe to summary table; add real provider env vars
  (LM_API_KEY/LM_BASE_URL, KIMI_CODING_API_KEY, ALIBABA_CODING_PLAN_*,
  ANTHROPIC_BASE_URL, COPILOT_API_BASE_URL); fix faq "Windows: not natively".
- user-guide: fix broken `hermes -w -q` (->-z) and `hermes logs --tail` (->-f);
  language list 8->16; aux slots 8->11; docker separate-dashboard claim;
  _SECURITY_ARGS -> _BASE_SECURITY_ARGS.
- features: curator prune_builtins truth + missing CLI verbs; codex-runtime aux
  keys (context_compression->compression, vision_detect->vision); kanban
  terminate endpoint + promote/reassign/schedule/diagnostics/edit + per-profile
  cap; mcp mTLS (client_cert/client_key); built-in-plugins nemo_relay +
  teams_pipeline; api-server run approval endpoint; computer-use frontmatter.
- features N-Z + integrations: StepFun step-3-mini->step-3.5-flash; web-search
  backends 4->8; tool-gateway image-model IDs; voice-mode STT/TTS enums; remove
  phantom `rl` toolset; nous-portal status subcommand.
- messaging: WeCom typing/streaming cols; telegram transport default edit->auto;
  sms host default; simplex/ntfy `gateway setup` + pairing approve; line
  smart-chunking; matrix MATRIX_DM_AUTO_THREAD.
- developer-guide: build-a-plugin code examples (register_command signature,
  ContextEngine/ImageGenProvider/MemoryProvider ABCs); model-provider-plugin
  entry-point group hermes.plugins->hermes_agent.plugins; PLUGIN.yaml->plugin.yaml;
  agent-loop stale LOC; web-search-provider phantom crawl().

PR coverage (2-week window, 149 feat PRs):
- desktop.md refreshed for ~15 shipped features (zh-Hans switcher, rebindable
  shortcuts + zoom + Cmd+K, status-bar model picker + YOLO toggle, session-by-id
  + archive, multi-profile concurrent + cross-profile @session, composer history,
  Providers pane, per-profile remote hosts, Grok OAuth, aux-pin warning).
- configuration.md gateway-streaming default corrected to per-platform.
- tool-gateway.md free tool pool entitlement note.

 The `display.language` setting translates a small set of static user-facing messages — the CLI approval prompt, a handful of gateway slash-command replies (e.g. restart-drain notices, "approval expired", "goal cleared"). It does **not** translate agent responses, log lines, tool output, error tracebacks, or slash-command descriptions — those stay in English. If you want the agent itself to reply in another language, just tell it in your prompt or system message.

 **Fresh final (Telegram):** Telegram's `editMessageText` preserves the original message timestamp, so a long-running streamed reply would keep the first-token timestamp even after completion. When `fresh_final_after_seconds > 0` (default `60`), the completed reply is delivered as a brand-new message (with the stale preview best-effort deleted) so Telegram's visible timestamp reflects completion time. Short previews still finalize in place. Set to `0` to always edit in place.

-Streaming is disabled by default. Enable it in `~/.hermes/config.yaml` to try the streaming UX.
+:::note Per-platform streaming defaults
+The master `streaming.enabled` switch is `false` by default — nothing streams until you flip it. Once enabled, streaming is decided **per platform**: Telegram ships with `display.platforms.telegram.streaming: true` (streams) and Discord with `display.platforms.discord.streaming: false` (does not). So after enabling streaming, Telegram streams out of the box and Discord stays on whole-message replies until you change its toggle. You can adjust these per-platform switches from the dashboard's **Channels** toggles or directly in `~/.hermes/config.yaml`.
