EnigmaGrid 0.4.2 — GPU duty control fix

GPU work/rest timing now respects the requested duty ratio when scoring takes longer than expected. Previously, a one-second cap on rest could make low GPU budgets run more intensely than intended. The client also checks pause controls during the rest period.

This is a recommended, optional Windows update. It preserves contributor identity and settings; the minimum supported version remains 0.4.0. GPU settings control work/rest timing, not an exact percentage in Task Manager.

Validation: source CI, official Windows build, frozen worker/tray and installer lifecycle tests, real 0.4.1-to-0.4.2 optional/required accept-and-decline scenarios, active-work update boundaries, and rollback after an intentionally failed health check. The candidate also passed worker/tray self-tests on Surface with Intel Iris Plus OpenCL detected. This is not a claim of testing every GPU.

Download EnigmaGridSetup.exe for installation. The ZIP is the update package. Updates are authenticated with the project's Ed25519 signature, and both Windows assets have GitHub build attestations. The installer is not Authenticode-signed.

The research campaign is unchanged. No decryption breakthrough is claimed.
