feat(channels): add Feishu/Lark messaging channel integration

- Frontend: add feishu to PLATFORM_REGISTRY with official tutorial guide
- Tauri backend: add feishu read/save/verify in messaging.rs
- Web backend: add all messaging platform handlers to dev-api.js
- Feishu verification uses tenant_access_token API (feishu/lark dual domain)
- Plugin: @openclaw/feishu@latest auto-installed on save
- Guide links to official OpenClaw Feishu plugin article
