Retro Display Lab v0.8.5

DMG-01 motion topology and lean artifact checks

This release contains the DMG-01 connected-director-branch motion fix from v0.8.4 and simplifies how its generated physical LUT is validated.

• Normal npm test no longer recomputes the full director solver on every Node/CPU architecture.
• The fast stored-artifact check verifies SHA-256 for the generator, drive model, material ensemble, and solver; requires the stored physical and motion-topology gates to pass; and verifies that the report and Shader surrogate are the same generated pair.
• Full numerical reconstruction remains available explicitly as npm run test:dmg-physics-full and passed before publication.
• This removes recurring macOS/Linux libm last-digit failures without weakening stale-input, hand-edited-artifact, or failed-physics detection.

Validation

• Local full repository npm test passed.
• Explicit full DMG physical reconstruction passed.
• Branch and v0.8.5 tag GitHub Actions both passed on Node 18, 22, and 24.
• Runtime shader artifacts are unchanged from v0.8.4; the release remains open for a fresh reporter/KONKR device confirmation on issue #1.

v0.8.4 remains available for provenance; v0.8.5 is the recommended download.
