* ✨ feat(builtin-skills): add bot platform setup guide reference

Add `references/bot-setup-guide` to the LobeHub skill with step-by-step
credential setup instructions for Discord, Slack, Telegram, Feishu, Lark,
QQ, and WeChat. Enables agents to guide users through platform bot
configuration end-to-end via the `lh bot` CLI workflow.

* ✨ feat(builtin-skills): split bot setup guide into per-platform references

Replace the single `bot-setup-guide` reference with 7 platform-specific
guides (Discord, Telegram, Slack, Feishu, Lark, QQ, WeChat), each with
detailed step-by-step credential setup instructions matched to the actual
schema fields. Also update the LobeHub skill description to trigger
activation when users mention connecting messaging platform bots.

* ♻️ refactor(builtin-skills): nest bot platform guides under references/bot/ directory

Move bot setup guide resource keys from flat `references/bot-*` to
nested `references/bot/*` so they appear as a subfolder in the
skill resource tree instead of a flat list.

* 🐛 fix(builtin-skills): fix Telegram --app-id and WeChat CLI setup guide

- Telegram: add required --app-id (numeric bot ID from token prefix)
  to the lh bot add command; explain how to extract it from the token
- WeChat: remove incorrect CLI QR scan flow; lh bot connect only starts
  an already-configured provider and does not perform QR auth.
  Redirect users to Web UI for initial WeChat setup

* 📝 docs(builtin-skills): clarify WeChat setup steps with exact UI navigation

Guide users to click 消息频道 (Message Channel) in the left sidebar
then select WeChat to get the QR code, matching the actual UI layout.
