docs: reconcile docs with code across last 3 releases (#54254)

Audited the last 3 releases (v2026.5.28..main) against the docs site and
fixed code-vs-docs drift:

- slash-commands: add /moa, /prompt, /pet, /hatch, /timestamps
- cli-commands: add hermes pets / project / desktop / whatsapp-cloud +
  dashboard register; correct --insecure (now a deprecated no-op);
  add gateway migrate-legacy + enroll --wake-url + dashboard --skip-build
- environment-variables: document the remaining ~48 env vars (SimpleX,
  Photon, Teams adapter, per-platform *_ALLOW_ALL_USERS, home-channel vars,
  IRC, Brave/Krea/Notion/Linear/Airtable/Tenor keys, QQ_SANDBOX) — full
  OPTIONAL_ENV_VARS (265) now covered
- configuration: document tool_loop_guardrails, goals, prompt_caching,
  network, onboarding, dashboard config blocks
- toolsets/tools-reference + tools.md: add coding/project toolsets and
  read_terminal/project_* tools; remove the stale messaging toolset and
  send_message agent tool (removed in #47856); drop stale RL-training prose
- messaging: new IRC channel page (adapter shipped without docs) + index
  row + sidebar + env vars
- pets: document the /hatch AI generation pipeline + Nous/OpenRouter image
  backend
- web-dashboard: document the bearer-token / TokenPrincipal service auth path
- purge agent-callable send_message references across guides/features and
  the research-paper-writing skill (tool removed in #47856)

Verified: docusaurus build succeeds; all authored internal links resolve.

 :::tip MCP Tools
 In addition to built-in tools, Hermes can load tools dynamically from MCP servers. MCP tools appear with the prefix `mcp_<server>_` (e.g., `mcp_github_create_issue` for the `github` MCP server). See [MCP Integration](/user-guide/features/mcp) for configuration.
