docs: ratify sensorium afferent ADRs + acknowledge arc in work-sequencing

Authority-ratified per the ADR-0207 convention (Accepted (ratified DATE)):
- ADR-0181 (audio), ADR-0197 (vision), ADR-0208 (environmental loop),
  ADR-0209 (sensorimotor afferent) -> Accepted (ratified 2026-06-03).
  All four are implemented + test-backed (0208/0209 falsifiability deeply
  verified in the lookback; 0181/0197 backed by CRDT-merge/compiler/mount/
  eval-gate suites, all green in the 182-test sweep).
- ADR-0198 deliberately NOT ratified: partially-implemented spike (Gap A +
  fail-closed efferent gate landed; \xc2\xa73 verdict-lowering + motor decoder
  deferred behind a dedicated motor governance ADR).

CLAUDE.md Work Sequencing now records the sensorium/modalities arc as a
sanctioned parallel track that does not displace the near-term sequence and
is disjoint from the GSM8K serving path. Markdown only; no test asserts ADR
status or the work-sequencing text.

+The afferent sensorium/modalities arc (ADR-0013 -> 0181/0197/0208/0209; ADR-0198
+reserves the efferent/motor half) is a **sanctioned parallel track** — not part
+of the near-term sequence above and not licensed to displace it.  It is disjoint
+from the GSM8K serving path (no `generate.derivation` / `core.reliability_gate`
+import), so it cannot regress the serving metric; its efferent half stays gated
+behind ADR-0198's fail-closed boundary and a dedicated motor governance ADR
+(ratified afferent ADRs carry `Accepted (ratified ...)`; ADR-0198 stays a
+partially-implemented spike).
