Summary by cubic

Ports the 8-inch UI and assets, unifies multi-board compile flags, and now exports UI structure JSON at runtime. The build is simpler: submodules removed, CMake tuned for POSIX/debug, and FreeType font loading fixed.

• New Features

  • Added Charger_PreDefine.h to centralize targets (AC/DC, MT7628, AM3354, SSD202, cabinet, 4.3").
  • Added fonts (D-DIN-PRO-600-SemiBold.otf, calibri.ttf, calibrib.ttf).
  • Added UI fragments under assets/fragment/ (connectors, charging states, errors, detailed data, language picker, keypad, help/billing, no-price).
  • Runtime export of UI structure descriptions to aid debugging and asset verification.

• Refactors

  • Removed .gitmodules (no lvgl, lv_drivers, FreeRTOS submodules).
  • CMake: min 3.10, force gcc, set Debug, unset cached USE_FREERTOS, add include paths; POSIX-first with USE_FREERTOS opt-in.
  • Improved debug interface for local demos.
  • Fixed FreeType to load/render new .otf/.ttf assets.

^{Written for commit 6559ffb. Summary will update on new commits.}
