refactor: simplify path displays and remove sensitive config data

- Add CustomSkillsMiddleware to show ./skills instead of full paths
- Enable virtual_mode for FilesystemBackend in local mode
- Display "." instead of ~/.deepagents/{bot_id} in system prompt
- Remove backend_host and masterkey from robot project config
