C, C++ and background lifecycle

These small plugins demonstrate the versioned entry point, allocator ownership, callback exception boundary and cancellable worker jobs.

Build

Set EPICTUNER_SDK_ROOT and use cmake --preset sdk followed by cmake --build --preset sdk in this directory. The build produces C and C++ libraries plus development manifests.

epictuner-plugin-check --development --manifest out/plugin.json
epictuner-plugin-check --development --manifest out/plugin-c.json
epictuner-plugin-check --development --manifest out/plugin-background.json --expect-log "background sum=55"

Windows executable names end in .exe. A successful checker run covers startup, ordered event delivery, heartbeat and stop. The background example computes a synthetic sum and returns it through the dispatcher. These are nonvisual ABI examples, additional to the eight gallery examples.

See lifecycle.cpp, lifecycle.c and background.cpp. Run the exported conformance tests to check C and C++ shared-module negotiation, including incompatible-version rejection.
