docs(link): the phase the measurement cancelled, and the 452 wrong pictures it found on the way (Phase 6)

§16 planned deep animation keys and a bulk-fill switch. Measuring first changed
the phase: a complete one-direction animation set is 174,453 frames / 281.5 MB
(not the ~119,000 / ~117 MB §11 estimated), every frame carries its own centre
and 23,818 of 26,274 actions have frames of differing size — and the site
displays still pictures. So none of it was built (§11.2, org lead 2026-09-11);
`body/<id>/a<n>/f<k>` stays named in §5 and refused in practice.

§4.10 is what the walk found instead. A body's actions are a contiguous band and
the next body's begin immediately after, so one action past the ceiling is a real
record of another creature: 643 of 795 legacy bodies pass every check there and
452 are byte-identical to body+1's action 0. `Animations.GetAnimLength` is not
the ceiling — it disagrees with the index arithmetic on one body of this client,
by nine actions.

What shipped: the 73 bodies with no art at action 0 (a horse at `body/820/a23`),
the catalogue key carrying its action, the atlas join that reads it instead of
hardcoding `a0`, and the ceiling that makes the fallback walk safe. Catalogue
1,022 -> 1,095; EXTRACTOR_VERSION 2 -> 3; protocol stays 8.
