Release 0.18.0 + automated FreeDOS QEMU smoke - #2
Conversation
Fully-automated counterpart to the manual run_freedos_qemu.sh: overlays the FreeDOS image (no mutation), stages the interpreter and a SYSTEM-terminated smoke on C:, injects the run plus poweroff into the image's startup batch, boots headless, and diffs OUT.TXT against the golden file. Local-dev only (needs qemu, a FreeDOS qcow2, mtools, nbd, and passwordless sudo); CI keeps using the DOSBox-X path. Exercises the binary on a real FreeDOS install rather than DOSBox-X emulation.
Cross-language linking (link BASIC into C/Fortran, call C from BASIC via '$EXTERN), the v0.18 codegen/perf batch (paren string-comparison fix, --no-gc-check/--fast-math, larger 32-bit caps, process-local DATE$/TIME$), and the automated FreeDOS QEMU smoke. Bumps GW_VERSION and updates the banners, CHANGES.TXT, and the development history table.

tests/run_freedos_qemu_auto.shis a fully-automated counterpart to the manualrun_freedos_qemu.sh: it overlays the FreeDOS image (never mutating the original), stages the interpreter and aSYSTEM-terminated smoke on C:, injects the run plus poweroff into the image's startup batch, boots headless, and diffsOUT.TXTagainst the golden file. Verified locally (PASS, ~22s, clean APM poweroff). It is local-dev only (needs qemu, a FreeDOS qcow2, mtools, nbd, and passwordless sudo), so it is not a GitHub-CI job; CI keeps using the DOSBox-X path. It complements that path by exercising the binary on a real FreeDOS install rather than DOSBox-X emulation.Both DOS smoke paths (DOSBox-X and this QEMU one) pass against the freshly-built 16-bit interpreter.
