Mythic Masters: beast detail hill climb to 9/10, rounds 2+ (from #2854) #3459

Continues the beast detail loop from #2854 (round 1, PR #2860), which had sunk to the bottom of the issues. Part of #2802 (the beasts from 3/10 to great). The animation and graphics climb is #3455; this one is the beast models only.

Where it stands

3/10, the owner's score for the beasts in #2802. Agent judges run about 2 points high on visual climbs (#2943: judges 5, owner 3), so read a judge's number as a direction.

One round

One worker, from main:

1. bun run beasts, judge the contact sheets in apps/mythic-masters/blender/out/, score every beast out of 10, and put the scores in the PR.
2. Pick the three lowest and name what reads wrong (bare back, sawtooth rim, flat face, blob legs, tiny head, tube legs).
3. Fix it with an existing part in the sheet first. Only add a part to blender/beast.py when no part can do it, with a row in its field list and a README line.
4. Rebuild, check the feet and wing counts still match, rescore with a fresh judge (BEFORE vs NOW), and keep the change only if the score went up.

Rules that stay: one sheet always builds the same GLB, and every sheet's feet come out as rig tips.

Ending a round

Comment here, first line Score: x/10 (target 9), then the shots, then Next: <the judge's top gap>. The PR says "Part of #", never a closing word. Then hop forward (bun run climbs has the baton text).
