fix(plugins): expose host Claude plugins + skills to container

Root cause of '容器里看不到任何 SK':
- Container's /root/.claude was an isolated named volume (empty)
- Host plugins live in ~/.claude/plugins/cache/<marketplace>/<plugin>/<version>/
- installed_plugins.json embeds ABSOLUTE paths like /Users/$USER/.claude/...
  which don't resolve in container

Fix:
1. docker-compose.yml
   - Bind-mount ${HOME}/.claude/plugins -> /root/.claude/plugins (ro)
   - Bind-mount ${HOME}/.claude/skills  -> /root/.claude/skills  (ro)
   - Pass HOST_HOME env var
2. scripts/container-entrypoint.sh (new)
   - If HOST_HOME != HOME, symlink HOST_HOME -> /root so the absolute
     paths inside installed_plugins.json resolve (e.g.
     /Users/gongzhiyong/.claude/... -> /root/.claude/...)
3. Dockerfile
   - Install entrypoint, wire it into ENTRYPOINT via tini

Verified: all 4 installed plugins (oh-my-claudecode, superpowers,
frontend-design, planning-with-files) + 3 skills (agent-browser,
find-skills, omc-reference) visible in container.
