Plugin API policy list adds session.root, prompt.read, and ui.panes as permitted actions
What
The internal manifest of known/permitted actions that plugins can request through Claude Code's API grew three new entries: session.root, prompt.read, and ui.panes. These join existing entries like session.cwd, flag.value, and the ui.blit family.
Why
This expands what plugins are allowed to access or do through the API, likely enabling plugin features that need the session's root directory, read access to prompts, or control over UI panes.
