Plugins hooks on devcontainers can't call upon plugin location

- VS Code Version: 1.129.0
- OS Version: Windows/WSL/Devcontainer
- Feature (e.g. agent/edit/ask mode): plugin hooks
- Selected model (e.g. GPT 4.1, Claude 3.7 Sonnet): any
- Logs:

/bin/sh: 1: c:\Users\USER\.vscode\agent-plugins\github.com\obra\superpowers/hooks/run-hook.cmd: not found

Steps to Reproduce:

Plugins defined on plugins, with the correct syntax from https://code.visualstudio.com/docs/agent-customization/agent-plugins#_hook-configuration-format are not found inside a devcontainer.

Tried to install from inside the container the plugin, but then it doesnt pick up.

In this plugin example, it runs a command that injects skills into the context, the skills are from the plugin itself. Hooks that runs commands inside are ok, but those that need external files, in this case, from the plugin files are lost because of where it run vs where the files are.
