fix(skills): correct TTS/STT providers, add missing platforms/commands in hermes-agent skill

Fixes verified via 5-container parallel testing against v0.8.0 codebase.

Critical fixes:
- TTS providers: replace nonexistent kokoro/fish with actual minimax/mistral/neutts
- STT providers: add missing mistral (Voxtral Transcribe)
- Testing section: remove `source venv/bin/activate` (no venv dir in project)

Expanded coverage:
- Provider table: 13 → 22 entries (add Gemini, xAI, Xiaomi, Qwen OAuth, MiniMax CN, etc.)
- Platform list: add BlueBubbles (iMessage) and Weixin (WeChat), clarify Open WebUI
- Slash commands: add 14 undocumented commands (/approve, /deny, /branch, /fast, etc.)
- Toolsets: add 4 missing (messaging, search, todo, rl)
- Troubleshooting: expand from 6 to 10 sections with practical deployment fixes
  (Copilot OAuth 403, gateway linger, WSL2 systemd, Discord intents, etc.)

Minor fixes:
- agent/ directory description expanded
- delegation config keys completed
- /restart noted as gateway-only
- hermes honcho noted as plugin-dependent

@@ -19,7 +19,7 @@ What makes Hermes different:
 
 - **Self-improving through skills** — Hermes learns from experience by saving reusable procedures as skills. When it solves a complex problem, discovers a workflow, or gets corrected, it can persist that knowledge as a skill document that loads into future sessions. Skills accumulate over time, making the agent better at your specific tasks and environment.
 - **Persistent memory across sessions** — remembers who you are, your preferences, environment details, and lessons learned. Pluggable memory backends (built-in, Honcho, Mem0, and more) let you choose how memory works.
-- **Multi-platform gateway** — the same agent runs on Telegram, Discord, Slack, WhatsApp, Signal, Matrix, Email, and 8+ other platforms with full tool access, not just chat.
+- **Multi-platform gateway** — the same agent runs on Telegram, Discord, Slack, WhatsApp, Signal, Matrix, Email, and 10+ other platforms with full tool access, not just chat.
 - **Provider-agnostic** — swap models and providers mid-workflow without changing anything else. Credential pools rotate across multiple API keys automatically.
 - **Profiles** — run multiple independent Hermes instances with isolated configs, sessions, skills, and memory.
 - **Extensible** — plugins, MCP servers, custom tools, webhook triggers, cron scheduling, and the full Python ecosystem.

+Common gateway problems:
+- **Gateway dies on SSH logout**: Enable linger: `sudo loginctl enable-linger $USER`
+- **Gateway dies on WSL2 close**: WSL2 requires `systemd=true` in `/etc/wsl.conf` for systemd services to work. Without it, gateway falls back to `nohup` (dies when session closes).
+- **Gateway crash loop**: Reset the failed state: `systemctl --user reset-failed hermes-gateway`
+
+### Platform-specific issues
+- **Discord bot silent**: Must enable **Message Content Intent** in Bot → Privileged Gateway Intents.
+- **Slack bot only works in DMs**: Must subscribe to `message.channels` event. Without it, the bot ignores public channels.
+- **Windows HTTP 400 "No models provided"**: Config file encoding issue (BOM). Ensure `config.yaml` is saved as UTF-8 without BOM.
+
+### Auxiliary models not working
+If `auxiliary` tasks (vision, compression, session_search) fail silently, the `auto` provider can't find a backend. Either set `OPENROUTER_API_KEY` or `GOOGLE_API_KEY`, or explicitly configure each auxiliary task's provider:
+```bash
+hermes config set auxiliary.vision.provider <your_provider>
+hermes config set auxiliary.vision.model <model_name>
