v1.8.1 — Auto tune recovery and clearer streaming controls

Download and extract the complete Windows x64 ZIP, then run SteamLinkVRSettings.exe. The package includes the .NET and Windows App SDK runtimes.

• Auto tune detects stopped video between trials, reconnects the same captured PC with
  at most two recovery attempts per run, and requires fresh output before measuring again.
  Reconnection stops a stale headset streaming client before restarting it, and restores
  the connection before using SteamVR settings APIs. Cleanup errors retain the original cause.
• A brief low-output interval no longer ends a trial after only a few seconds. Completed
  windows still require enough encoded video; invalid counters and changed settings remain errors.
• Wireless advice now requires fresh measurements and avoids recommending more bandwidth
  from an underloaded scene. Current link problems take priority over an older sweep result.
• A measured ceiling must have adequate video output and a completed clean confirmation
  before it can be offered, applied or saved. If confirmation fails, a lower clean candidate
  receives its own confirmation instead of being assumed safe.
• Pending gaze-quality edits survive background polling and navigation. Irrelevant controls
  are disabled, and scrolling no longer accidentally changes dropdown selections.
• Back to stock no longer mistakes an exited SteamVR process for a running driver during
  shutdown. After saving the recovery profile, it disables automatic reapply so a later
  restoration error cannot re-arm the old encoder override on the next restart.
• Compact windows have wrapping action buttons, readable Overview metrics, a more accessible
  live graph and Auto tune start button, and grouped radio/capacity details.
• Live verification completed 64 valid Auto tune trials in 25:05, produced three labeled
  recommendations and restored the starting settings. A separate deliberate stream-drop test
  verified automatic recovery and continued measurement. Short screens retain limited-confidence
  labels, and observed streaming hitches remain visible.
• Live Back to stock verification restored the exact original driver, removed saved tuning
  overrides, and resumed Valve-controlled VBR/single-pass encoding with no pending-policy warning.
• Validation: 334 managed tests, seven native tests and 30 compositor assertions passed.
  One legacy patcher test was skipped because its external driver fixture was not provided.
