Versioned Plugin System (Experimental)

What: A comprehensive plugin versioning and caching system that stores plugins by version in a dedicated cache directory, supporting multiple installation scopes (user/project).

How to enable: The feature is controlled by the tengu_enable_versioned_plugins experiment flag.

Details:

• Plugins are cached at ~/.claude/plugins/cache/{scope}/{plugin-name}/{version}/
• New V2 file format (installed_plugins_v2.json) supports multiple installations per plugin
• Intelligent component copying analyzes plugin manifests to copy only necessary files
• Version resolution uses manifest version, git SHA (12 chars), npm registry, or timestamp
• Automatic migration from V1 format when enabled
