refactor: restructure project for multi-agent extensibility

- Migrate source to packages/client and packages/server directories
- Namespace all Hermes-specific code under hermes/ subdirectories
  (api/hermes/, components/hermes/, views/hermes/, stores/hermes/)
- Add hermes.* route names and /hermes/* path prefixes
- Upgrade @koa/router to v15, adapt path-to-regexp v8 syntax
- Fix proxy path rewriting: /api/hermes/v1/* → /v1/*, /api/hermes/* → /api/*
- Fix frontend API paths to match backend /api/hermes/* routes
- Fix WebSocket terminal path to /api/hermes/terminal
- Add proxyMiddleware for reliable unmatched route proxying
- Add profiles route module and hermes-cli profile commands
- Update CLAUDE.md development guide with new architecture
- Add Chinese README (README_zh.md)
- Add Web Terminal feature to README
