docs: reflect rollback to v3 on frank-default-large (Kairic experiment retired)

AGENTS.md topology table + runtime sections, docs/index.md deployment
diagram, docs/kairic-edge.md (retired experiment, perf summary), and
docs/ciru-activefpx-promptforge.md (active again) all restored to the
v3 reality. Remaining Kairic references are inside the retired reference
page itself.

+[[ciru-activefpx-promptforge]] (v3) on 2026-08-22.
+
+Performance summary of the experiment: the IU4 lane accelerated prefill
+1.5-2.3x over v3 at all depths, but prose decode was 15-26% slower
+(inherent to the release: the IU4 lane does not accelerate M1 target
+decode). Reasoning-off fast-greedy mode was ~8% faster per token than
+production chat, and roughly 2x faster per turn from halved output volume.
+The v3-era experience, including the 400 errors from the argmax fast path
+rejecting non-greedy requests, motivated the revert.
