Related GitHub Issue

Closes: #12307

Description

Adds an examples/agentboot-p2pclaw/ directory containing:

1. roomodes-example.yaml -- Example .roomodes entry defining an "AgentBoot" custom mode with pre-configured system prompts for bare-metal hardware detection, OS installation workflows, and agent bootstrapping on the P2PCLAW network.

2. mcp-config-example.json -- Ready-to-use MCP server configuration snippet for connecting Roo Code to the P2PCLAW MCP server (https://github.com/Agnuxo1/p2pclaw-mcp-server). Users add this to their own MCP settings -- no core architecture changes needed.

3. README.md -- Documentation page with quick start guide, example workflows (research agent creation, bare-metal bootstrapping), and links to all related projects.

This is a lightweight, documentation-first approach as discussed in the issue. No changes to Roo Code core -- just example configurations that users can copy into their own projects.

Test Procedure

• Verified JSON syntax of mcp-config-example.json
• Verified YAML structure of roomodes-example.yaml against the .roomodes schema
• Documentation reviewed for accuracy and completeness
