feat: auto-install WeChat article tools during install (#80)

* feat: auto-install WeChat article tools during agent-reach install

WeChat (微信公众号) deps are now auto-installed during 'agent-reach install':
- Python packages: camoufox[geoip], markdownify, beautifulsoup4, httpx, miku_ai
- Tool repo: wechat-article-for-ai cloned to ~/.agent-reach/tools/

No login or configuration needed — works out of the box like YouTube/RSS.
Updated README tables to reflect zero-config status.
Also covers safe mode and dry-run.

* feat: auto-install WeChat + add channel-setup reference to SKILL.md

1. WeChat auto-install during 'agent-reach install':
   - pip install camoufox[geoip], markdownify, bs4, httpx, miku_ai
   - clone wechat-article-for-ai to ~/.agent-reach/tools/
   - covers safe mode and dry-run
   - README tables: WeChat → zero-config

2. SKILL.md improvements:
   - Added 'configure' triggers to description
   - Added references/channel-setup.md with install steps for all
     login-required platforms (Twitter, XHS, Douyin, LinkedIn, Boss)
   - Principle: user only provides cookies, agent does everything else

* simplify: point to install.md URL instead of bundled reference

No need to maintain a separate channel-setup.md. Just tell agents
to fetch install.md when they need setup instructions.
