Nub 0.1.8

A Node augmentation batch: an interactive-TUI hang fix, native-addon ESM imports, WebAssembly and ShadowRealm unflagging, and the NODE_COMPAT tree-wide opt-out.

Terminal foreground handoff

Interactive full-screen TUIs — Nx, Turbo — hung unkillably under nub run, with Ctrl-C unreachable. Since 0.1.6 the child runs in its own process group, but that group was never handed the terminal foreground, so any raw-mode terminal read raised SIGTTIN and stopped the process while Ctrl-C went to Nub instead of the child.

On the interactive path, Nub now hands the terminal foreground to the child's process group after spawn, and a guard restores Nub's foreground on child exit. While the child owns the terminal, the redundant SIGINT forward is suppressed — the kernel already delivers Ctrl-C to the foreground group directly — and the 0.1.6 single-SIGINT guarantee is preserved. (#32, fixes #27)

Expanded feature matrix

Three experimental Node features are now auto-injected on the Node versions that require the flag, consistent with Nub's existing posture of backfilling a feature where it was flagged. --node opts out.

Worker execArgv filtering also strips --harmony-* and --experimental-shadow-realm from child Worker threads to avoid bad-option startup aborts on Node versions where those flags are absent. (#31, #33)

Tree-wide compatibility opt-out

Setting NODE_COMPAT=1 (or true/yes, case-insensitive) forces zero-augmentation mode tree-wide — the persistent, inheritable form of --node. Because env vars propagate to descendants, one export in your shell, .envrc, or CI config covers the entire process tree. Version resolution and Node provisioning stay active; only runtime augmentation is disabled. It composes with --node — either one forces compatibility mode. (#34)
