Settings & plugin defaults

The gear in the top-right opens application-wide Settings. All values live in the database and OpenAI options apply on the next request — no restart needed.

• OpenAI / AI provider keys and options — used by the chat, spec import, enhance and per-operation generation.
• Mock AI — a checkbox that returns canned responses (useful for demos or when offline).
• Support legacy — when on, legacy / terminal-player surfaces (Terminal player sidebar link, screen icons) become visible for legacy workspaces.
• Plugin defaults — opens the same configuration dialog used per workspace, but in global mode. Values entered here are copied into new workspaces when their plugins are enabled.
