Companion module for the DiGiCo S31 with an iPad relay (v1)

Bitfocus Companion 5 connection module (ESM, @companion-module/base ~2.1.3,
runtime node22) for the DiGiCo S21/S31. It occupies the console's single
iPad slot, controls per-channel sends/assigns to one buss, aux send
level/on/pan, mutes, faders and snapshots, and relays any number of DiGiCo
iPad apps through to the console byte-for-byte.

The S31's iPad extension was probed live: it speaks the SD/DiGiCo Pad OSC
tree (console receives on 8000, replies only to the configured iPad port
9000). tools/mock-s31.js emulates the console and test/selftest.js runs the
link + relay end to end against it. docs/design-v2.md is the brief for the
generic v2 rewrite.
