feat: add remote-bridge skill (deploy and manage remote servers)

[varaprasadreddy9676]

Summary

Adds remote-bridge to the .experimental catalog — a skill for deploying and managing remote Linux servers over SSH and rsync from Codex.

• Syncs local directories to remote servers via rsync
• Runs shell commands on remote servers
• Tails remote log files
• Restarts services
• Full deploy pipeline (sync → restart → logs on failure)

MCP server

The skill depends on the remote-bridge MCP server, distributed as an npm package:

npm install -g remote-bridge-cli

Source: https://github.com/varaprasadreddy9676/remote-bridge
npm: https://www.npmjs.com/package/remote-bridge-cli

Safety features

• --delete is opt-in (off by default) — prevents accidental remote file deletion
• require_confirmation: true on a target forces a dry-run preview before any sync executes
• local_path must be set explicitly to prevent syncing the wrong directory
• Agent instructions enforce dry-run-first on production targets

Checklist

• Placed under .experimental
• SKILL.md follows the frontmatter + body format from existing curated skills
• agents/openai.yaml has interface and dependencies matching the render-deploy pattern
• MCP dependency declared with transport: stdio
• No scripts or assets required (binary installed via npm postinstall)
