test_apps/workspace_minimal_d3d11_win fails to compile (orphaned XR_EXT_app_launcher.h since #308)

[dfattal]

Summary

test_apps/workspace_minimal_d3d11_win/main.cpp does not compile. It still #includes the launcher extension header and resolves/exercises the launcher PFNs, but the runtime launcher (and XR_EXT_app_launcher.h) were removed in #308 (c74f1770b — "remove runtime launcher; add input-grab + SBS overlay (spec 17→19)"). This is pre-existing — not caused by #370.

Repro

scripts\build_windows.bat test-apps

main.cpp(49): fatal error C1083: Cannot open include file: 'openxr/XR_EXT_app_launcher.h': No such file or directory

Details

The orphaned launcher surface in main.cpp:

• #include <openxr/XR_EXT_app_launcher.h> — L49 (header deleted in workspace: move app launcher entirely out of runtime (large, ~600 LOC removal) #308)
• PFN decls — L146–150 (pfnClearLauncher, pfnAddLauncherApp, pfnSetLauncherVisible, pfnPollLauncherClick, pfnSetRunningTileMask)
• get-proc lookups — L184–188
• launcher smoke-test block — L718–743 (XrLauncherAppInfoEXT, xrClearLauncherAppsEXT, etc.)

CI impact

None today. build-windows.yml's test-apps job only builds cube_handle_d3d11_win, so main CI stays green; the breakage is latent (only surfaces via local build_windows.bat test-apps, which builds every test app).

Fix

Remove the launcher include + the 5 launcher PFNs (decls, lookups, and the L718–743 exercise) from the smoke test, so it again compiles and resolves only the live XR_EXT_spatial_workspace surface.

Context

This smoke test is the canonical "resolve every workspace PFN + walk the lifecycle" coverage app. #370 (cursor-depth shell-ownership, spec 22) already touched it — it swapped the removed xrWorkspaceHitTestEXT for the new xrSetWorkspaceCursorDepthEXT — but intentionally left the #308 launcher fallout out of scope. This issue tracks that cleanup.
