ogar-fma-skeleton: GUID tier model — [container:member], located/cascade, 12+4

Operator design download (2026-06-23, with the papillary-muscle worked
example + the located/cascade "heel" distinction):

- guid.rs: the brutal uniform GUID as a stack of [256:256] tiers, each the
  same scale-free relation [container:member] (Galaxy:planet, country:city,
  bodypart:bone, cm²:mm², residue:atom). Tier{container,member}, Guid with
  per-tier accessors, classid/heel/leaf, same_family ("identity attached to
  family node" = tiers..LEAF equal, identity varies).

- HhtlMode::{Located, Cascade} — the "heel" duality. Located (Cesium):
  HEEL is the literal position, HHTL = spatial_tier Morton, location-
  preserving — the BONE case (bones ARE the anchor). Cascade (ontology):
  HEEL is a classification rung (Anatomy…PapMuscle), no spatial address,
  HHTL = ontology_tier — the MUSCLE case (classified, then projected onto).
  Both share the LEAF familyNode:identity and the 16-byte key.

- EdgeBlock: the 12+4 edge block (12 in-family local relations + 4
  out-of-family inherited connector interfaces), one byte per slot — the
  papillary-muscle family-node template.

- LeafTile{family_node, identity} = the [bodypart:bone] leaf.

Additive — the working bone atlas (FamilyAddress) is untouched. 22 tests
green (16 + 6 new), clippy-clean. Doc §5b records the tier model + the
located/cascade duality + the splat-projects-onto-the-class framing.
