fix(scrape): make vision OCR a per-bundle allowlist, not a corpus sweep

The first vision pass OCR'd every large image and, because the "transcribe
the table" prompt makes qwen render ANY image as a markdown table, it turned
60 product UI screenshots into junk "tables" in the corpus. In practice the
only image-only DATA in this corpus is the release-schedule matrix — the
upgrade-compatibility matrices etc. are already native HTML tables, no OCR
needed.

- Add BundleSpec.ocr (default False); the runner passes the OCR-enabling
  session only for bundles that opt in. Set ocr=True only on
  morpheus_release_schedule.
- Purge the 60 screenshot cache entries (keep the release-schedule one). The
  next --force refresh regenerates every other page's .md WITHOUT the bogus
  "## Image transcriptions" section, cleaning the deployed corpus + index.
- Update vision.py / refresh.yml docs to the allowlist model.

Also add scripts/vision_report.py — a self-contained HTML report pairing each
OCR'd source image with its transcription (uncertain-first) for accuracy
inspection. Regenerate anytime from corpus/.vision-cache/.

Verified: release schedule still transcribes (cache hit); cache is back to 1
entry; other bundles now pass no session so their images are left alone.
