docs(meta): add asset pipeline and remote terminal proxy ideas to scratchpad

Two new scratchpad entries: asset generation pipeline improvements
(registry, status tracking, prompt versioning) and a remote terminal
proxy concept for mobile monitoring of Claude Code permission prompts.

 - Pipeline to create postcards for each world — visuals for in-game dossiers
 - Investigate using Veo to create gate transition movies — based on planetary profiles, postcards, and game visual style
 - Capture discussion with Gemini about setting up a 3D to 2D pipeline
+- Improve asset generation pipeline: proper asset registry, status tracking per asset, prompt storage/versioning, pre-sprint prompt preparation pass to maintain visual/audio cohesion across batches
+- Remote terminal proxy for Claude Code — mobile notification + interaction bridge for monitoring progress away from desk. Full feature scope:
+  - Capture permission prompts across all terminals/worktrees in a project
+  - Push notifications to phone (Ntfy/Gotify/Pushover/custom — self-hostable)
+  - Summary of last assistant message for context (what Claude is doing and why it's asking)
+  - Support AskUserQuestion mode: render multiple-choice options, free-text input
+  - Support permission approve/deny with the tool call details
+  - Basically a full terminal proxy that adapts to Claude Code's interactive elements
+  - Starting point: peon-ping already hooks into the right events (PermissionRequest, Notification, Stop, etc.) via ~/.claude/hooks/
+  - Hook event JSON includes: hook_event_name, notification_type, session_id, cwd, permission_mode
+  - Gap: hook event data may not include prompt content (tool call details, AskUser question text, multiple choice options) — investigate what's in the full event payload
+  - Architecture: extend peon-ping's send_notification pattern to push to a remote service, add a response channel back to the terminal
