mavend: a position resolves against the digest she last read (V-516)

The router names a position ("2", "last") or a demonstrative ("this"),
because only the daemon has the list. surfacedItems records the item ids
she read out, in the order she said them, and only for items she could
actually say: one Praxis returned without a title has no position in what
he heard.

resolveSurfacedPosition maps the reference to an id before dispatch, and
its second return says whether the turn is still Praxis's. A position that
names nothing keeps the turn and clears the slot, so the capability asks
which пункт -- he said "второй пункт" and deserves to hear there is no
second one. A demonstrative that resolves to nothing gives the turn BACK,
because "я это сделал" was probably never about a пункт. "это" also needs
the list to hold exactly one item: pointing at one of five is a guess, and
a wrong guess here transitions the wrong item.

No TTL, unlike the pending confirmation. A stale position resolves to an
item Praxis will report as already acknowledged, which is a harmless
answer, where a stale confirmation would execute something.

Measured, make eval-reach, classifier + ONNX: 16/30 -> 27/30 overall,
praxis 0/12 -> 11/12, lifecycle 0/5 -> 5/5, attention 0/7 -> 6/7, hexis
and none unchanged, p50 20.6ms -> 16.5ms. make eval-router: 60/84, 0 false
clarifies, and no failure in that list comes from a stage-0 decision.
Details and the two judgement calls in docs/evals/2026-08-05-praxis-reach.md.
