Remove archived VxCleanup product and unreferenced assets

- Delete Source/vxstudio/products/cleanup (no plugin target since VXClarity/VXRefine replaced it)
- Excise cleanup-only regression tests; drop the Cleanup stage from chain tests;
  substitute Deverb/Tone where Cleanup was used as a generic stage
- Remove VXCleanup help content and version constant
- Delete assets/deepfilternet/models/aggressive.onnx (unreferenced, 15 MB)
- Delete assets/rebalance/models/openunmix_umxhq_spec PyTorch weights (136 MB;
  runtime uses the converted ONNX in openunmix_umxhq_spec_onnx)
- Delete stale voice_corpus batch-audit snapshot reports

Verified: VXStudioAnalyserTests 7/7 pass; VXStudioPluginRegressionTests 74/75
(the one failure, testLevelerImprovesLevelConsistencyOnHotInstrumentMix, is
pre-existing on HEAD and unrelated)

-<h1>VXCleanup</h1>
-<p>Corrective voice cleanup for mud, harshness, breaths, plosives, sibilance, and general tonal trouble. It is subtractive repair before enhancement.</p>
-<h2>How to use it</h2>
-<ul>
-<li>Raise Cleanup until the distracting problems start to fall away.</li>
-<li>Increase Body if the result becomes too thin.</li>
-<li>Use Focus to steer the correction toward low-mid cleanup or more presence/air-region control.</li>
-</ul>
-<h2>Example settings</h2>
-<ul>
-<li>Muddy spoken voice: Cleanup 55%, Body 55%, Focus 45%.</li>
-<li>Harsh, breathy voice: Cleanup 60%, Body 50%, Focus 70%.</li>
-<li>Light corrective tidy-up: Cleanup 35%, Body 55%, Focus 55%.</li>
-</ul>
-<h2>Practical scenarios</h2>
-<ul>
-<li>Dialogue that needs cleanup before any enhancement.</li>
-<li>Speech with boxiness, spit, or low-end bumps.</li>
-<li>Preparation stage before proximity, tone, or final compression.</li>
