Malte UblandClaude Opus 5.5 51e9812493 Call into Node.js from compiled programs with @scriptc/node
Scope-B milestone NI-1, API side: the explicit call API that replaces the
build container's hand-written node subprocess (api patch 09).

- The new package @scriptc/node exports callSync(specifier, name, ...args)
  and call(...). The module loads with require() from the calling module;
  arguments and results cross as JSON copies; a thrown Error crosses as its
  nearest intrinsic class with its message and string code, other thrown
  values as JSON copies; callSync refuses a function that returns a
  promise. Its Node implementation runs the calls in-process with the same
  copies, so a program prints the same under Node and compiled.
- The compiler lowers calls to the named or namespace imports
  (node-api-import.ts, lower-node-island.ts) to the nodeIsland.callSync
  and nodeIsland.call libCalls: the calling module's real path, the
  specifier, the export name and the boxed argument array, with the result
  checked against the declared type like `JSON.parse(s) as T`. Arguments
  and results whose types are not JSON data are refused at build time, and
  the functions and the namespace refuse as values.
- Corpus programs 6800-6803 (sync and async results, errors, process.exit
  from Node with the program's exit listeners, Node's pending timers
  keeping the program alive) run under Node and as binaries that load
  libnode; `// @requires-libnode` skips them where SCRIPTC_LIBNODE names no
  pack (until the pack CI matrix publishes packs). The node-island harness
  covers loading Node only on the first call, the beside packaging, a
  missing pack, a pack of another Node version or bridge ABI, and the
  executable's symbols.
- Release tooling publishes @scriptc/node with the other packages.
