Split T-Deck firmware from microReticulum examples/lxmf_tdeck/ into its own repo. microReticulum is consumed as a git submodule dependency pinned to feat/t-deck. All include paths updated from relative symlinks to bare includes resolved via library build flags. Both tdeck (NimBLE) and tdeck-bluedroid environments compile successfully. Licensed under AGPLv3.
