Default Gemini adapter to yolo mode and add API access prompt note

Gemini CLI only registers run_shell_command in --approval-mode yolo.
Non-yolo modes don't expose it at all, making Paperclip API calls
impossible. Always pass --approval-mode yolo and remove the now-unused
policy engine code, approval mode config, and UI toggles.

Add a "Paperclip API access note" to the prompt with curl examples
via run_shell_command, since the universal SKILL.md is tool-agnostic.

Also extract structured question events from Gemini assistant messages
to support interactive approval flows.
