The `Unit*` getters and `SpellCanTargetUnit` answered nil for chained tokens like `raid3target` or `party1target`, so a raid-assist addon's main-tank frame stayed empty.
Every getter and `SpellCanTargetUnit` resolves its token through `0x515970` and then reads the guid's object (`0x468460`); see `UnitHealth 0x517511`/`0x51752d` and `SpellCanTargetUnit 0x6e6d3a`.
A token with target hops now resolves to a guid in the VM and reads a per-guid snapshot. A new feed pushes one for each held unit a chain ends on. `SpellCanTargetUnit` keeps its verdicts by guid. The three target, target-of-target and NPC snapshot builders are folded into one.
Tests: `UnitName`/`UnitHealth("raid3target")` and `UnitExists("pettarget")` answer the chained unit, `SpellCanTargetUnit("party1target")` answers its verdict, and plain tokens are unchanged.
