refactor(delivery): use workspace out as artifact root

 - `/mcp` supports the default `list` behavior (and explicit `/mcp list`) to show configured MCP servers and registered MCP tools.
 - Agent runtime config should be hot-reloaded from the active `config.json` for safe in-process fields such as `tools.mcpServers`, `tools.web.*`, `tools.exec.*`, `tools.restrictToWorkspace`, `agents.defaults.model`, `agents.defaults.maxToolIterations`, `agents.defaults.contextWindowTokens`, `agents.defaults.maxTokens`, `agents.defaults.temperature`, `agents.defaults.reasoningEffort`, `channels.sendProgress`, and `channels.sendToolHints`.

For local QQ images, prefer the documented rich-media `file_data` upload path together with the public `url`, and keep the URL-only flow as a fallback for SDK/runtime compatibility.

 - `/skill` shells out to `npx clawhub@latest`; it requires Node.js/`npx` at runtime.
 - `/skill uninstall` runs in a non-interactive context, so keep passing `--yes` when shelling out to ClawHub.
 - Treat empty `/skill search` output as a user-visible "no results" case rather than a silent success. Surface npm/registry failures directly to the user.
