Release v0.3.1-alpha Added: project-level dmx.toml universe → device mapping. See Changes.md for details. Highlights: - <project>/dmx.toml encodes which DMX adapter drives which universe - 'serial:<USB_SERIAL>' resolves to a stable /dev/serial/by-id path - Two-pass resolution prevents auto-detect from stealing explicit bindings - --print-dmx-resolution CLI flag for verifying wiring - Workspace 0.3.0-rc2 -> 0.3.1-alpha
