build: multi-target mise.toml with BOARD_TARGET env var

Usage:
  mise run compile                              # default (e32r35t)
  BOARD_TARGET=waveshare_s3 mise run compile    # Waveshare 4.3"
  BOARD_TARGET=e32r35t mise run all             # build + upload + monitor
  BOARD_TARGET=waveshare_s3 mise run install-libs  # install target-specific libs

Each target gets its own FQBN, build flags, library set, and port detection.
