DOC: State final-state behavior in V&V deliverables

[imikejackson]

Summary

The V&V deliverables were describing our own development history — which cycle, pass, or PR
resolved a given defect — rather than the state of the shipped code. A V&V report should say what
the code does today and how that differs from DREAM3D 6.5.171, if at all.

Commit 1 — state final-state behavior

• Replaces development-process framing across 37 V&V reports, deviation files, and provenance
  sidecars in OrientationAnalysis, SimplnxCore, and ITKImageProcessing. Phrases such as
  "fixed during this V&V cycle", "fixed this pass", and "fixed by this PR" are restated as the
  resolved condition.
• Reclassifies two Algorithm Relationship rows from "Port with bug fix" to "Port with one
  inherited bug corrected", which is what those entries actually document — a legacy 6.5.171
  defect corrected on the SIMPLNX side, not a SIMPLNX defect.
• Renames two provenance sidecars to match their filter names, following the convention used by
  the rest of the directory: read_ang_test.md to ReadAngDataFilter.md, and
  6_6_read_ctf_data_2.md to ReadCtfDataFilter.md.

Pre-fix/post-fix comparisons are deliberately retained wherever they establish that a regression
test is load-bearing — those describe code states, not our workflow, and removing them would
weaken the coverage argument.

Commit 2 — name the affected releases

Deviation entries told users they were on an "earlier SIMPLNX release" without saying which. Those
now name actual DREAM3D-NX versions:

• Every deviation entry touched here was resolved after 7.4.1 (2026-03-23), so no released
  version carries the fix. The entries say so explicitly instead of implying an upgrade is
  available.
• Where the introducing change is known the window is narrowed: the CAxisSegmentFeatures
  first-seed defect (PR BUG: Fixes issue when segmenting features with a +1 feature count #1466, 2025-11-14) and the ComputeNeighborhoods regression (PR BUG: New implementation for ComputeNeighborhoods filter #1485,
  2026-01-08) each affect 7.4.1 only, since 7.4.0 (2025-10-27) predates both.
• Adds docs/dream3d_nx_release_dates.md as the version-to-date reference these entries cite.

Notes

No deviation findings, measured values, deviation IDs, or test references are changed anywhere in
this PR.

GroupMicroTextureRegionsFilter is deliberately excluded; its V&V documents are rewritten in the
open Group MicroTexture Regions PR and would conflict here.

Test Plan

• Documentation-only change; no source files touched, so no build or test impact
• Markdown table integrity verified (column counts unchanged on all modified table rows)
• Renames recorded as pure renames (100% / 99% similarity), no content lost
• Release windows cross-checked against docs/dream3d_nx_release_dates.md and the merge dates
  of the introducing and resolving PRs
