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.

  (captured from a clean profile, no secrets/personalization).

 The Tool Gateway is a **paid-subscription** feature. Free-tier Nous accounts can use Portal for inference but don't include managed tools — [upgrade your plan](https://portal.nousresearch.com/manage-subscription) to unlock the gateway.
 
+Some accounts are also entitled to a **free tool pool** — a small managed-tool allowance that covers gateway tool calls without a paid subscription. When a free pool is available, the gateway surfaces it and shows a setup prompt on first use, so you can opt in and start using managed tools right away.

 ## Mix and match
 
 The gateway is per-tool. Turn it on for just what you want:
