leetcrypt 2cfa388879 feat(cardex): image-search harvester + genre-diverse character library ...

Grow the hh card-art library so common VM types stop reusing one portrait.

- scripts/imgharvest.py: keyless DuckDuckGo image-search harvester — downloads
  many stills per character and runs them through charvest's crop/quality/dedup
  pipeline (static art crops far cleaner than motion-blurred video frames).
- scripts/harvest_roster.sh: batch roster (Pokemon/Digimon/Yu-Gi-Oh) sized to
  the live VM card types. Library now 37 characters / 99 portraits.
- charvest: top-anchor the head+shoulders crop for tall full-body art so faces
  are no longer clipped.

chardex matcher — stop same-type VMs collapsing onto a single face:
- fold a per-(VM,character) hash jitter INTO the score, not just a tie-break
- diminishing returns on extra type matches so a strong single-type face can
  compete with a dual-type one
- halve tier affinity and cap the keyword bonus
- stop-word rarity/boilerplate words that were polluting keyword overlap
Result: 20 distinct faces across the library. The one remaining cluster
(Sigilyph on the Psychic/Flying recon-scanner VMs) is coherent purpose-
matching — a scanner-themed bird on the scanner VMs — not a bug.

NOTE: assets/characters/ are third-party franchise IP with NO established reuse
license — quarantined, internal WIP only, do not distribute/merge/publish
(licensing record in docs/character-art-licensing.md).
