developer_vitality 1.1: age attributes match Attribute Initialize

Vitality 1.0 counts into <attr>_age1, _age2 and _age3 while Attribute
Initialize's Age toggles create _age0, _age1 and _age2, so only two
lined up and the accumulator never had an attribute to write to. 1.1
renames the counters in order: the one that resets on sign change is
_age0, the one that never resets _age1, the accumulator _age2. The
internal nodes are named for what they count. Verified on a saturated
frame, a sign flip, and an input without age attributes.

1.0 stays for hips that read the old names, with help pointing at 1.1.
developer.md and the audit list both versions.

 > Alongside: `developer_attribute_composite` gained vector and further scalar operations (`ffd6c75`), `developer_analysis` writes its statistics into the `<attr>_info` dictionary that `developer_attribute_initialize` creates, whose range is one vector2 key (`8e87ec2`, `43ba011`). No hip in the repo used any removed type; hips elsewhere that did will load those nodes as empty placeholders.
