dasungd in FDS/OS

The controller for the user's grayscale Dasung Paperlike 13K is maintained as an FDS Rust workspace member. It provides USB keepalive, reconnect/watchdog handling, configuration, and a local control socket.

Use the FDS integration and usage guide for build commands, base packaging, native s6 supervision, Pi display configuration, and validation limits. From the repository root, run make dasung followed by make dasung-test. These targets do not operate the workstation's live monitor.

IMPORT.md records the source task and original input hashes. VALIDATION.md is the original workstation acceptance record; its references to the original README and systemd installation are historical. The FDS target uses the native s6 integration documented in the guide above. Pi boot and corrected physical cold-start recovery are not yet verified.
