// Contract battery for the JSPI libcontext coroutine backend
// (kicad/thirdparty/libcontext/libcontext.cpp under PCBJAM_JSPI). The harness
// (tests/apps/standalone/jspi-coroutine) is a wx-free MiniCoro that mirrors
// tool/coroutine.h's protocol exactly — INVOCATION_ARGS, callerStub with the
// finish_fcontext hook, jumpIn/jumpOut, CONTINUE_AFTER_ROOT — over the real
// libcontext.cpp. 18 cases: create/run/finish, yield chains, nested
// call-in-call routed by enterer inference, RunMainStack payload propagation,
// ghost-resume refusal (dead tombstones, sentinel-shaped), mid-body release census, phantom-release refusal (running record + enterer chain), destroy-while-parked containment.
//
// Output contract: per-case "[JSPI_CORO] CASE <name> PASS|FAIL" then
// "[JSPI_CORO] SUMMARY passed=<n> failed=<n>".
