This release makes an unhandled worker failure fatal, matching node:worker_threads, closes a brand-boundary leak in the package manager's config-file resolution, and keeps the post-target argument separator verbatim across every runner verb.

Runtime

A Worker created with no error listener that failed to load or threw at top level previously exited 0 in silence — Nub's browser-shape Worker is an EventTarget, which drops an event with no listener. It now mirrors node:worker_threads.Worker: an unhandled error is re-thrown on the main thread (uncaught exception, exit 1, stack printed), still interceptable via process.on('uncaughtException'). The listener-present path is unchanged. (#244)

Package manager

The embedded engine no longer reads or writes a brand-specific user or project config file under Nub, closing a brand-boundary leak in settings resolution. A Nub project's config surface stays .npmrc plus the sanctioned NUB_* env knobs. (#242)

CLI

nub watch now keeps the post-target -- verbatim, matching nub <file>, run, and exec. The target token ends runner parsing and everything after it forwards byte-for-byte, as in node and pnpm 10 — -- is neither required nor special-cased. (#239)
