feat(install): split into core + optional channels with --channels flag (#237)

Base install now only sets up lightweight zero-config channels (Web, YouTube,
GitHub, RSS, Exa, V2EX, Bilibili basic). Optional channels (Twitter, Weibo,
WeChat, Xiaoyuzhou, XiaoHongShu, Reddit, Bilibili full, Douyin, LinkedIn)
are installed on demand via --channels flag.

- Add --channels param to install subcommand
- Extract twitter/xhs/reddit/bili into independent install functions
- Remove heavy deps (weibo/xiaoyuzhou/wechat/twitter-cli/xhs-cli) from
  default _install_system_deps() and _install_mcporter()
- Cookie import only triggers when cookie-needing channels are selected
- Doctor output: inactive optional channels summarized in one line
- install.md: two-step flow (basics → ask user which channels)
