Extract permission mode display logic into shared utilities for better reusability and maintainability. Add PermissionModeTone type and related helpers to centralize mode-based styling rules across components. Update components to use new PermissionModeOption type for consistent permission mode presentation.
Implements bidirectional sync of permission/model modes between CLI sessions and web app. Adds Codex-specific permission modes (read-only, safe-yolo, yolo) alongside Claude's modes. Web can now control CLI session state via RPC set-session-config handler, while CLI broadcasts state changes through keep-alive payloads. UI controls are flavor-aware, showing appropriate modes for Claude vs Codex vs Gemini. Type centralization in api/types eliminates circular dependencies.
