Release DisplayXR Runtime v2.3.0 · DisplayXR/displayxr-runtime

Highlights

Input-provider plug-in channel (ADR-034). DisplayXR now supports a second vendor plug-in type: input providers that surface motion controllers from external tracking sources. This release ships the in-tree sim_input reference provider, the net_input loopback-TCP provider with a public wire protocol + feeder, and an SDK-gated Ultraleap Tier-1 provider (LeapC hands as motion controllers) — with the OpenXR action system exercised end-to-end across in-process, IPC, and WebXR paths.
Official Khronos CTS in CI. The conformance harness was resurrected (#830, pinned to openxr-cts-1.1.54) and now runs the full suite on release tags — including a real conformance fix: XrEventDataSessionStateChanged.time was 0.
Vendor-shippable geometry publisher (#817 / ADR-033): compositor-published window geometry enables Wayland windowed weaving, with a schema gate and packaging contract so vendors can ship it.
