-- Cross-engine I/O round-trip: write/read text and lines, parse JSONL,
-- and format/parse a timestamp. Pins that the Cranelift JIT helpers
-- jit_rd/jit_rdl/jit_wr/jit_wrl/jit_jpar/jit_rdjl/jit_dtfmt/jit_dtparse
-- agree with tree/VM on success, and that their type-error paths now
-- surface VmError::Type through JIT_RUNTIME_ERROR instead of silently
-- returning nil. (The type-error paths are unit-tested directly; this
-- file pins the happy paths so the examples harness exercises them on
-- every engine.)
