Settings rail (Devices active) with This device (getIdentity), Discovered nearby
(new getDevicesScan bridge → `codeburn devices scan --format json`), and Paired
(getDevices perDevice). Pairing/approve/pull/visibility/combine are M1 visual
affordances (mutations = M2); share status is process-local so not shown as
authoritative. Settings uses a title-only bar (no period/provider).
Implemented by Codex gpt-5.5 (high); committed by Fable (git blocked in Codex sandbox).
