- Add ScreensaverType::McpScreen to DisplaySettings enum, toString/fromString - Add 'MCP Screen' option to the Display settings screensaver dropdown - New McpScreensaver (Screensaver subclass): creates full-screen lv_canvas on the overlay, allocates framebuffer in SPIRAM, registers canvas pointer in McpSystemState, shows 'Waiting for LLM...' until first draw command arrives - Wire McpScreensaver into DisplayIdle::activateScreensaver() switch - McpSystem::ensureOverrideScreen() now calls displayidle::findService()-> startScreensaver() instead of launching McpOverrideApp — canvas appears automatically on any LLM draw command - Remove McpOverrideApp (replaced by screensaver), deregister from Tactility.cpp - Remove mcpOverrideEnabled from McpSettings — no longer needed - Simplify McpSettingsApp: remove Screen Override toggle, update info text to direct users to Settings -> Display -> Screensaver -> MCP Screen
