release: v2.1.17

Render upload progress from fractional transfer values while keeping the visible percentage rounded. Move the green fill with a linear compositor transform and cover the 92-to-93 percent transition with monotonic frame-level Electron assertions.

Keep Electron UI verification listeners loopback-only so development validation no longer raises a Windows Firewall prompt under electron.exe. Extend the public source allowlist with the focused network safety regression coverage.
