Build every screen from one shared core plus a small file per board, the same firmware as before (0.2.84)

The two board profiles (5,000 lines each, 87 % the same text) become packages/core.yaml and one file per
board under packages/boards/: the hardware, a table of 84 sizes and font sizes, 18 hooks with the lines of C++
only that board adds inside a shared lambda, and the board's own sections. packages/cyd.yaml and
packages/guition.yaml keep their names and places (a screen installed from ESP Screens builds as before);
home-like-2432s028.yaml and guition-4848s040.yaml become the same entries for a checkout.

The firmware stays 0.2.70: the C++ ESPHome generates for each board, through the checkout profile and
through the GitHub package route, was compared line by line with the old profiles' (docs/TEST_RESULTS_0284.md).
tools/check_packages.py replaces tools/generate_packages.py; tools/profiles.py gives the tests and tools the
three files as one; docs/PROFILES.md says how the files fit together and how a board is added.
