docs(kiro): archive the superseded roadmap; status notes on specs

A4: roadmap-2026-09-04.md moves to .kiro/archive/steering/ so it no longer
loads as steering (roadmap.md and safety-net.md replaced it); roadmap.md's
pointer follows it. overview.md's spec table is recounted from tasks.md and
spec.json (adds ai-service-plane, harnessx-removal, learned-decision-engine,
pre-push-safety-net; drops the stale "active one"), and the module line now
cites the regenerated audit: 150 modules, 145 load-bearing, 5 standalone,
0 orphaned; 1,964 tests collected.

A5: a dated status note at the top of the requirements (or brief) of 16
specs: retired, superseded, dormant or complete, and for
model-grounded-detection the removal of judge/calibrate/execution (closing
the Req 10 execution-tier option). spec.json phase corrected to
implementation-complete where every task is checked (model-grounded-
detection, propose-adjudicate-prove, tree-sitter-overlay-extra,
corpus-seeded-mechanisms, pair-corpus-honesty); openrouter-sast-harness gets
a spec.json with status retired. Nothing deleted, no spec moved.

 > **Retired 2026-09-30:** HarnessX was removed by `harnessx-removal`; the agentic plane is ax (`ai-service-plane`),
 > and evolutionary proposals come from the plane memory. The HarnessX specs in the table above are history.
