[FEATURE] Headless/programmatic plugin installation

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Claude Code supports headless/programmatic prompting , https://code.claude.com/docs/en/headless, by passing the -p to run in non-interactive mode. There should be a way to install and manage plugins in headless/non-interactive mode. This would allow you to install and use plugins programmatically and within CI/CD pipelines.

Proposed Solution

I'd like to be able to run claude -p "/plugin install my-plugin@my-plugins"
